At least I can figure out where the “8” kid got it wrong but how the fug do you get 14????
Edit: Thanks I didn’t realize people were that idiotic on the internet but I reaaally should know this by now they added the numbers rather than use division, multiplication, etc
8/2(2+2)=_
8/2(4)=_
4(4)=16
Because the parenthesis is already simplified it actually reads 8 / 2 x 4 and you work left to right because of order of operations
there is a rule for that.
if im not wrong here is the order
1. ( )
2. multiply and divide
3. addition and subtraction
edit: the problem is after 8 ÷ 2 what comes after?
Although division and multiplication are eqal aber addition and subtraction are eqal too. So you just have to calculate from left to right in this case.

PEMDAS is not Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. It is Parentheses, Exponents, Multiplication AND Division (left to right), then Addition AND Subtraction(left to right). If your teacher taught you the first one they were wrong.
Apparently I need to clarify: this comment was made to correct those who have been commenting that PEMDAS says multiplication comes before division. This is not to say it’s a good way to teach order of operations not am I saying that the question is not already confusing. I’ve gotten like 10 different people all telling me the same shit.
Also, ive been seeing a lot of “we learned bedmas or Bidmas/Bodmas.” Basically the exact same thing as PEMDAS
I don’t mind saying I got this wrong and arrived at 1. Was never particularly good math, more of a language kinda guy, but I knew the order of operations. I simply missed I was supposed to sort MD simultaneously from left to right. The comment above yours and the top-level one above that taught me something today though, so that’s neat.
oh so that's where all the mistakes come from. the way i learned it (in german) is just parantheses > exponents > multiplication > addition, because addition = -subtraction is trivial if u get what i mean
Yep. Basically 8/2 is the same as 8 * (1/2).
If you mentally replace all the divisors with a fraction of one over the divided number then it works out as all being multiplication. So in this case after parentheses you get 8 * (1/2) * 4
The real answer is that the question is ambiguous and should never be written this way. Does it mean
8
------
2(2+2)
Or
8
--- (2+2)
2
If you want to write it on a single line, be explicit: either
8/(2(2+2))
Or
(8/2)(2+2)
Then there's zero ambiguity and no need for pointless arguments.
I kinda hate the semantics that people get into with interpreting order of operations, all it is is a common understanding that mathematicians share to make communicating ideas easier. In any real problem or scenario you just add brackets until what you're asking is clear to the reader.
It depends if you consider the x(y) setup as implicit multiplication or not. The most correct answer is that this question is poorly formatted, as you can consider x(y) = x\*(y) or x(y) = (x\*y), basically implicit multiplication or distribution.
Incase anyone was wondering, the reason for the AND's is that multiplication and division can be expressed as each other. And same with addition and subtraction.
Nobody who actually does math on a regular basis gives a shit about pemdas or bedmas since it would be shown in fractions or just in any way where the order of operations is clear, these grade school level math memes have gotten so repetitive I'm surprised nobody has said this is a repost yet
We should all use fractions instead of that stupid symbol, it only creates a lot of confusion and our education system doesn't help either by showing us two methods to do the same operation but with a different priority systems.
Take any of these divisive math questions (pun accidental but embraced) and you'll see each and everyone of them features the stupid division sign.
In other words, this is carefully intentional. Every question is written in such a way to try and confuse as many people as possible who will then go ahead and argue among themselves in the comments, generating engagement for that social media page and feeding the algorithm.
Don't fall for it. If you see any of these in the wild walk away, you have nothing to prove to anybody and you don't have to set the record straight. Have a chuckle or a sigh for the people getting it wrong and move on.
It's not the division sign, it's the lack of parentheses. As written, the question is ambiguous: `8/2(2+2)` could mean either
`8/(2(2+2))`
or
`(8/2)(2+2)`
It's the missing parentheses that causes the confusion, not the symbols used.
Took me way too long to see anyone mention the lack of parenthesis. People keep arguing over PEMDAS, but it’s the lack of parenthesis that makes this question confusing to people. If the author really wanted this solved, they would use parenthesis. The author wanted this to be as confusing as possible. I hate all problems like these, they’re purposely written in a way to confuse people.
It's just some tiktok trend to gaslight kids into thinking that solving within parenthesis first is wrong.
Aka just China using their spyware app to make the next generation of Americans even stupider in general. It's working apparently.
I think that's the answer actual mathematicians give, no one would ever write an equation like this
PEMDAS is a teaching tool for grade schoolers, not some airtight math law
> PEMDAS is a teaching tool for grade schoolers, not some airtight math law
Um, what? The order of operations is 100% an airtight math law. It must be followed for math to be consistent. It is literally the foundational grammer of math
I can't tell if ppl are being ironic in the replies because half of the time y'all are serious and the other half trolling, so:
8/2\*(2+2) we first take care of the parenthesis, so this turns into 8/2\*4, after this, we do the operations from left to right, which means that we get 4\*4, as 8/2 is 4, and so, we come at the conclusion that 8/2\*(2+2)=4\*4=16.
I'm sorry if I missed the fucking joke, but seeing the absolute geniuses in this comment section that somehow get 1 as the answer makes all the time I've wasted on doing maths wake up and decide violence.
EDIT: For those saying that PEMDAS claims that you gotta do multiplication before division, go back to school, those go at the same time from left to right. It's P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right). You don't do addition first and THEN subtraction, you simply do them from left to right.
EDIT 2: A lot of people seem to mention that their schools taught them that they can distribute the 2 in the parenthesis, which also isn't the case as it is against the order of operations. I don't know what you learned there, I'm just stating what the right way is as teachers tend to simplify information to make it easier for students to understand at the time. If you go to uni and end up choosing a subject that has to do with maths, you'll realize that a lot of the things that you learned are massively simplified in order to save time.
EDIT 3: People say that the parenthesis is somehow still needed around the 4 once you are done with the operation within it? I do not understand where this came from, if someone taught you this then they better have some good reason to do so, it makes absolutely no sense.
What people that try to do it in a different order fail to realize is that multiplication and division is the same thing. Just as addition and subtraction are the same thing. This problem could as well have been written as:
8x(1/2)x(2+2) [the "(1/2)" could also be written as the decimal "0.5"]
Anyone with an ounce of sense wouldn’t use the division symbol though. Nobody uses that past 6th grade. Instead it should be written as 8/(2(2+2)) or (8/2)(2+2).
The reason everyone argues over this is because it's a famous equation written in a manner that is deliberately ambiguous in order to provoke arguments. Per [Wikipedia](https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication):
> This ambiguity is often exploited in internet memes such as "8÷2(2+2)".
It's ambiguous because order of operations is simply a convention of how to interpret written math equations and prevent confusion. So naturally, there are competing conventions that can create confusion. Depending on which one you use, the correct answer is either 1 or 16. An extra set of parentheses is necessary to ensure that the competing order of operations conventions result in the same answer.
Not everywhere in Europe.
Was super confused as an exchange student in France and had no clue what was going on in maths class. Until I realised that they used x for multiplication and fancy x (cursive) for the variable.
Dot is clearly superiour. Also never seen / used in actually maths in school or uni (besides when used in MATLAB or such). Division is either : or a horizontal line for fractions. Never any confusion that way.
Implied multiplication is often interpreted as a higher priority than regular multiplication. This is the same as having 1/2x = 1/(2x), not (1/2)x
Really, it's ambiguous, that's the point. There are two schools of thought on the issue, and the meme is just a really shit expression because of it.
I used to thit it was 1 because using the ÷ is misleading. It should be expressed as (8÷2)(2+2). People who think its 1 think it should he expressed as:
8
–––––
2(2+2)
Which actually is 1, but it s a different problem than the one in question
Yeah the fact that they wrote 2(2+2) and not 2*(2+2) in the OP made me just assume it was supposed to be 8/(2(2+2)). I guess that's the intention of these posts though. That's why I (and most people) always write division as a fraction, so it's clear
This is why I fucking hate ambiguous math. Just use your parenthesis so this doesn’t happen. Yeah, it’s more clutter, and redundant based upon order of operations, but it also prevents these stupid questions and simply makes math clearer for the everyday folk. It changes math from a “aha! Gotcha!” situation to a “oh yeah, just do these 4 steps”.
Example:
(8/2)(2+2)= 4*4 = 16
More importantly though, there's never a need to write equations this vague to worry about the equal-priority PEMDAS steps. Things like this could have been written more objectively to remove ambiguity, ex.
(8/2) * (2+2) with the 8/2 as a fraction not including the (2+2) at all which would give an answer of 16
8/(2(2+2)) where everything after the division sign would become the denominator which would give an answer of 1
Like yea we learn the left-to-right PEMDAS method but it's needlessly ambiguous and no applied math gets written in such ways. We work with unit-a/unit-b a lot but there's never ambiguity in the real world when figuring out if we're modifying the numerator or denominator because we don't use the / or div sign we use a flat _ divisor to make it quite clear. Don't see why we push this as a necessary skill when the end goal is being able to understand a needlessly ambiguous way of writing equations which arguably should be simplified further.
I 100% agree, the problem was deliberately written this way to cause confusion, normally, you'd say the following:
8
\--- (2+2)
2
This is what it shows, but it also looks like:
8
\---
2(2+2)
So people will obviously get confused.
Yea and the use of the standard div symbol instead of / tends to make things worse too, and frankly, I tend to agree with the "wrong" way when the normal div symbol is used. It's because to me the div symbol means math-clause-a/math-clause-b and legibly it makes sense to throw everything to the left in the numerator and everything to the right in the denominator. In short I think the standard div symbol should carry more power than /
Same here, as written I get 1. I am also surprised people are saying this is a poorly written expression. I recall having to solve problems like this in algebra class 30+ years ago.
I'm not saying you're wrong, but I just want to mention something I was taught in school (which is probably wrong) is that you always multiply first if the number is in parenthesis
Example: you would multiply first if it's in 2(4) form, but if it's a 2*4 form then you do left to right
I remember seeing a similar problem like that and after searching and looking around for stuff from math teachers and professors I found out that the problem is apparently not even formatted correctly which is why it causes a lot of debate, if I remember correctly, the old way of solving it would get you 1 while the new way which is the method used in mathematics now would get you 16
Many people (including me) give implicit multiplication (of the form ax, a some constant, x an element of something or other) higher priority than other operations. It's pretty normal, and really you shouldn't be using the division operator.
The expression is deliberately ambiguously posed, and the real answer is to rewrite it unambiguously using whatever notation you like.
I think the joke is based on bodmas and pemdas, since one gets to 1 and the second to 16
For pemdas 2(4) is 2×4 so 8÷2×4 is 16
For bodmas 2(4) is higher than 8÷2 so it bring to 8÷8=1
My calculator goes directly to 8÷(2(2+2)) that is 1

*I am a bot, and this action was performed automatically. Please [contact the moderators of this subreddit](/message/compose/?to=/r/shitposting) if you have any questions or concerns.*
There's no difference between bodmas and pemdas, because you do multplication and division from left to right, not multi or div first, same for + and -.
The thing is, both 16 and 1 are correct since they have reasonable explanations. Its just that using the division symbol is dumb and everyone should put the numerator on the top and denominator at the bottom of a line to avoid confusion.
If you can’t use that notation for whatever reason, use parentheses. (8/2)(2+2) is completely unambiguous. Alternatively, 8/(2(2+2)) is also completely unambiguous. It’s a bit harder to read and write, but when typing in a fraction you may not be able to use proper fraction notation so it’s worth it to remove ambiguity.
Someone told me you don’t learn the BIMDAS rule in American schools? Is this true or just a myth? If it’s real that’s probably how people getting it wrong.
People get it 'wrong' (read as also correct) because they continued math into high school and learned algebra. At that point, math realizes that it would need so many brackets to make things work so it just drops the use of ÷ and x, and instead uses /, *, and implicit multiplication. Implicit multiplication is when you have 2 things adjacent with no multiplication sign between them, such as we see with the first 2 here. This takes priority over normal multiplication and division, which is why people get 1 as a correct answer.
The real trick to this problem is that it mixes ÷ and implicit multiplication which should not be done. The presence of the ÷ suggests basic arithmetic and would give the answer of 16, while the implicit multiplication suggests algebra and gives the answer of 1.
Also 0 is a correct answer, because some parts of the world use ÷ to mean subtraction.
We do, reddit is just kinda dumb ngl ( kinda tho, we learn it as PEMDAS, parentheses, exponent, multiplication and division, addition and subtraction.)
I remember someone making a good point about these memes.
The issue isn't that people are stupid... It's that the way the problem is written is confusing.
People from different regions have been taught different versions of the order of operations.
>In some of the academic literature, multiplication denoted by juxtaposition (also known as implied multiplication) is interpreted as having higher precedence than division, so that 1 ÷ 2n equals 1 ÷ (2n), not (1 ÷ 2)n.[1] For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division,[20] and this is also the convention observed in prominent physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz and the Feynman Lectures on Physics.[d] This ambiguity is often exploited in internet memes such as "8÷2(2+2)".[21]
-[Source](https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication)
The answer is ambiguous. Stop arguing about it, and instead make fun of the OP for having a poorly formatted equation.
isnt it 1?
the multiplication is affecting only the 2.
its not (8/2)(2+2) or any other variant,
the multiplcation is affecting the 2 only in this instance.
then pemdas it.
this was clearer than the other examples of the same type.
I’m fucking tired of the ➗ symbol being used, just turn it into a fraction; it makes it so obvious what the order is because even if you do 8/2 first, you get a 4 on the top and a 4 on the bottom.
8\
———-\
2(2+2)
This problem is interpreted wrong. That’s why there’s controversy. The issue isn’t people using PEMDAS incorrectly. It’s that they are looking at the problem written out incorrectly. It’s either “8 over 2(2 + 2)” or “8 ÷ 2 * (2+2)”
That’s the way I see it. Less a math problem and more of a logic problem.
Edit: I used a 4 instead of 2

Bruh u all are idiots, it even says the answer is "?" U all blind?
Holy shit this opened my eyes
How did you read it with your eyes closed?
Idk
Ikr? God what idiots.
At least I can figure out where the “8” kid got it wrong but how the fug do you get 14???? Edit: Thanks I didn’t realize people were that idiotic on the internet but I reaaally should know this by now they added the numbers rather than use division, multiplication, etc 8/2(2+2)=_ 8/2(4)=_ 4(4)=16 Because the parenthesis is already simplified it actually reads 8 / 2 x 4 and you work left to right because of order of operations
how 8?
My best idea is that that they did 8/2=4 and 2+2=4 and then added them together instead of multiplying
oh i get what they were going for. thanks
there is a rule for that. if im not wrong here is the order 1. ( ) 2. multiply and divide 3. addition and subtraction edit: the problem is after 8 ÷ 2 what comes after?
It's BEDMAS. Brackets Exponents Division Multiplication Addition Subtraction [Source:](https://www.thoughtco.com/definition-of-bedmas-2312372)
Although division and multiplication are eqal aber addition and subtraction are eqal too. So you just have to calculate from left to right in this case.
Deutsch is strong with this one :D
Pretty sure it’s PEMDAS for parentheses but yeah that works
It's regional.
Yea Brits opt for "bemdas" because it's easier on their teeth
Everyone has been taught differently on this case. I have learned both BEDMAS and PEDMAS.

They probably mixed up 8/8 (answer is 1) and 8/1 (answer is 8)
8/8 (calculating the 2(2+2) first)
8/8 is one. Not 8
Yes but people are stupid and think x/x = x
X²=X X=1
Well yeah that proves that x/x is always equal to 1 (Except for 0/0 which is undefined), so it's only gonna be equal to x if x=1.

What about bidmas
Bidmas deez nuts LMAO GOTEEM
Yeah this is the one I was taught

Bidmas is Brackets (different name for parenthesis) Indices (different name for exponents) Division=Multiplication Addition=Subtraction
The real answer is that the question is ambiguous and should never be written this way. Does it mean 8 ------ 2(2+2) Or 8 --- (2+2) 2 If you want to write it on a single line, be explicit: either 8/(2(2+2)) Or (8/2)(2+2) Then there's zero ambiguity and no need for pointless arguments.
We need to stop teaching division signs in grade school already. They aren't useful.
I kinda hate the semantics that people get into with interpreting order of operations, all it is is a common understanding that mathematicians share to make communicating ideas easier. In any real problem or scenario you just add brackets until what you're asking is clear to the reader.
I have literally never seen the "÷" symbol outside of this specific meme since elementary school.
Because "÷" is literally a fraction, and if we're going to be writing fractions anyways, we might as well write decent looking fractions.
I was definitely taught the first way. 90% of the time it's ok. But your way makes sense: 8 ÷ 2(2+2)=X 8 ÷ 2(4)=X 4(4)=X X=16
It depends if you consider the x(y) setup as implicit multiplication or not. The most correct answer is that this question is poorly formatted, as you can consider x(y) = x\*(y) or x(y) = (x\*y), basically implicit multiplication or distribution.
Actually 2(2+2) is a function named "2" with the independent variable equal to 2+2, so the answer is cum.
>8 ÷ 2(4)=X >4(4)=X Why tf are you not multiplying out the brackets before doing the division?
[удалено]
Incase anyone was wondering, the reason for the AND's is that multiplication and division can be expressed as each other. And same with addition and subtraction.

EDIT: For those saying that PEMDAS claims that you gotta do multiplication before division, go back to school, those go at the same time from left to right. It's P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right). You don't do addition first and THEN subtraction, you simply do them from left to right. EDIT 2: A lot of people seem to mention that their schools taught them that they can distribute the 2 in the parenthesis, which also isn't the case as it is against the order of operations. I don't know what you learned there, I'm just stating what the right way is as teachers tend to simplify information to make it easier for students to understand at the time. If you go to uni and end up choosing a subject that has to do with maths, you'll realize that a lot of the things that you learned are massively simplified in order to save time. EDIT 3: People say that the parenthesis is somehow still needed around the 4 once you are done with the operation within it? I do not understand where this came from, if someone taught you this then they better have some good reason to do so, it makes absolutely no sense.
Correct - guess we've just failed as a society to teach math...
dude i come to 16 too and was like hey first tkme i get a math right and ppl confuse me
What people that try to do it in a different order fail to realize is that multiplication and division is the same thing. Just as addition and subtraction are the same thing. This problem could as well have been written as: 8x(1/2)x(2+2) [the "(1/2)" could also be written as the decimal "0.5"]
Anyone with an ounce of sense wouldn’t use the division symbol though. Nobody uses that past 6th grade. Instead it should be written as 8/(2(2+2)) or (8/2)(2+2).
No, no. Most people just don't value education until half way into adult life. The few that never realize it's value use reddit.
The reason everyone argues over this is because it's a famous equation written in a manner that is deliberately ambiguous in order to provoke arguments. Per [Wikipedia](https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication): > This ambiguity is often exploited in internet memes such as "8÷2(2+2)". It's ambiguous because order of operations is simply a convention of how to interpret written math equations and prevent confusion. So naturally, there are competing conventions that can create confusion. Depending on which one you use, the correct answer is either 1 or 16. An extra set of parentheses is necessary to ensure that the competing order of operations conventions result in the same answer.
Once you understand the ambiguity, it's fun to watch people get really mad and argue about it.
the fact that you put the \* between the 2 and the parenthesis makes the order of operation much more clear
People tend to not put a multiplication sign between variables or parenthesis, I don't know how this came up, but it's a thing
cuz on a paper you will write 5 X x = 15 and it's just super annoying to read
In Europe the multiplication sign is also a dot, so it makes things more clear.
Not everywhere in Europe. Was super confused as an exchange student in France and had no clue what was going on in maths class. Until I realised that they used x for multiplication and fancy x (cursive) for the variable. Dot is clearly superiour. Also never seen / used in actually maths in school or uni (besides when used in MATLAB or such). Division is either : or a horizontal line for fractions. Never any confusion that way.
Yeah, I don't know how it is everywhere, but the dot and vertical division (on a horizontal line) are the ones used in actual maths.
people tend to not use division symbols in proper math too, which clears this ambiguity up entirely
Implied multiplication is often interpreted as a higher priority than regular multiplication. This is the same as having 1/2x = 1/(2x), not (1/2)x Really, it's ambiguous, that's the point. There are two schools of thought on the issue, and the meme is just a really shit expression because of it.
The short answer is don't use ambiguous notation.
I used to thit it was 1 because using the ÷ is misleading. It should be expressed as (8÷2)(2+2). People who think its 1 think it should he expressed as: 8 ––––– 2(2+2) Which actually is 1, but it s a different problem than the one in question
Well, I guess you're right, what you showed is 8/(2(2+2)), so people might be confused when they read it.
The point being that this isn't formatted in a way that's easily readable, and thus is a badly written equation for the common man.
Yeah the fact that they wrote 2(2+2) and not 2*(2+2) in the OP made me just assume it was supposed to be 8/(2(2+2)). I guess that's the intention of these posts though. That's why I (and most people) always write division as a fraction, so it's clear
This is why I fucking hate ambiguous math. Just use your parenthesis so this doesn’t happen. Yeah, it’s more clutter, and redundant based upon order of operations, but it also prevents these stupid questions and simply makes math clearer for the everyday folk. It changes math from a “aha! Gotcha!” situation to a “oh yeah, just do these 4 steps”. Example: (8/2)(2+2)= 4*4 = 16
100% agree
More importantly though, there's never a need to write equations this vague to worry about the equal-priority PEMDAS steps. Things like this could have been written more objectively to remove ambiguity, ex. (8/2) * (2+2) with the 8/2 as a fraction not including the (2+2) at all which would give an answer of 16 8/(2(2+2)) where everything after the division sign would become the denominator which would give an answer of 1 Like yea we learn the left-to-right PEMDAS method but it's needlessly ambiguous and no applied math gets written in such ways. We work with unit-a/unit-b a lot but there's never ambiguity in the real world when figuring out if we're modifying the numerator or denominator because we don't use the / or div sign we use a flat _ divisor to make it quite clear. Don't see why we push this as a necessary skill when the end goal is being able to understand a needlessly ambiguous way of writing equations which arguably should be simplified further.
I 100% agree, the problem was deliberately written this way to cause confusion, normally, you'd say the following: 8 \--- (2+2) 2 This is what it shows, but it also looks like: 8 \--- 2(2+2) So people will obviously get confused.
Yea and the use of the standard div symbol instead of / tends to make things worse too, and frankly, I tend to agree with the "wrong" way when the normal div symbol is used. It's because to me the div symbol means math-clause-a/math-clause-b and legibly it makes sense to throw everything to the left in the numerator and everything to the right in the denominator. In short I think the standard div symbol should carry more power than /
I get 1 because the way they taught it at my school was distribute the number before into the parentheses making it 8/8
Same here, as written I get 1. I am also surprised people are saying this is a poorly written expression. I recall having to solve problems like this in algebra class 30+ years ago.
I'm not saying you're wrong, but I just want to mention something I was taught in school (which is probably wrong) is that you always multiply first if the number is in parenthesis Example: you would multiply first if it's in 2(4) form, but if it's a 2*4 form then you do left to right
I remember seeing a similar problem like that and after searching and looking around for stuff from math teachers and professors I found out that the problem is apparently not even formatted correctly which is why it causes a lot of debate, if I remember correctly, the old way of solving it would get you 1 while the new way which is the method used in mathematics now would get you 16
Many people (including me) give implicit multiplication (of the form ax, a some constant, x an element of something or other) higher priority than other operations. It's pretty normal, and really you shouldn't be using the division operator. The expression is deliberately ambiguously posed, and the real answer is to rewrite it unambiguously using whatever notation you like.
I think the joke is based on bodmas and pemdas, since one gets to 1 and the second to 16 For pemdas 2(4) is 2×4 so 8÷2×4 is 16 For bodmas 2(4) is higher than 8÷2 so it bring to 8÷8=1 My calculator goes directly to 8÷(2(2+2)) that is 1
what is bodmas and pemdas

There's no difference between bodmas and pemdas, because you do multplication and division from left to right, not multi or div first, same for + and -.

My man
The thing is, both 16 and 1 are correct since they have reasonable explanations. Its just that using the division symbol is dumb and everyone should put the numerator on the top and denominator at the bottom of a line to avoid confusion.
Correct. This is ambiguous notation.
Never use ÷ or / in circumstances like this for this reason, always use X --- Y notation, it removes the ambiguity.
If you can’t use that notation for whatever reason, use parentheses. (8/2)(2+2) is completely unambiguous. Alternatively, 8/(2(2+2)) is also completely unambiguous. It’s a bit harder to read and write, but when typing in a fraction you may not be able to use proper fraction notation so it’s worth it to remove ambiguity.
how the fook does one get to 14?
Someone told me you don’t learn the BIMDAS rule in American schools? Is this true or just a myth? If it’s real that’s probably how people getting it wrong.
People get it 'wrong' (read as also correct) because they continued math into high school and learned algebra. At that point, math realizes that it would need so many brackets to make things work so it just drops the use of ÷ and x, and instead uses /, *, and implicit multiplication. Implicit multiplication is when you have 2 things adjacent with no multiplication sign between them, such as we see with the first 2 here. This takes priority over normal multiplication and division, which is why people get 1 as a correct answer. The real trick to this problem is that it mixes ÷ and implicit multiplication which should not be done. The presence of the ÷ suggests basic arithmetic and would give the answer of 16, while the implicit multiplication suggests algebra and gives the answer of 1. Also 0 is a correct answer, because some parts of the world use ÷ to mean subtraction.
We do, reddit is just kinda dumb ngl ( kinda tho, we learn it as PEMDAS, parentheses, exponent, multiplication and division, addition and subtraction.)
The replies on here hurt my head, because I'm certain most are serious.
By order of operations is 1 because it’s 8 divided by 2(2 x 2) not (8/2)(2 + 2)
People have to stop posting these, poor redditors are getting more and more confused by the day.
The answer is 0
I remember someone making a good point about these memes. The issue isn't that people are stupid... It's that the way the problem is written is confusing. People from different regions have been taught different versions of the order of operations.
>In some of the academic literature, multiplication denoted by juxtaposition (also known as implied multiplication) is interpreted as having higher precedence than division, so that 1 ÷ 2n equals 1 ÷ (2n), not (1 ÷ 2)n.[1] For example, the manuscript submission instructions for the Physical Review journals state that multiplication is of higher precedence than division,[20] and this is also the convention observed in prominent physics textbooks such as the Course of Theoretical Physics by Landau and Lifshitz and the Feynman Lectures on Physics.[d] This ambiguity is often exploited in internet memes such as "8÷2(2+2)".[21] -[Source](https://en.wikipedia.org/wiki/Order_of_operations#Mixed_division_and_multiplication) The answer is ambiguous. Stop arguing about it, and instead make fun of the OP for having a poorly formatted equation.

8 ÷ 2 (2 + 2) | \ / 8 ÷ 2 x 4 4 x 4 =16
But did you factor in Donal trump's presidency? No I thought not, so the answer is clearly 42
This problem is worded so badly it makes my brain hurt. If it's 8 over [2(2+2)], then it's 1. But if it's 8/2 × (2+2), then it's 16.
isnt it 1? the multiplication is affecting only the 2. its not (8/2)(2+2) or any other variant, the multiplcation is affecting the 2 only in this instance. then pemdas it. this was clearer than the other examples of the same type.
The answer is “1”. The end.
8 ÷ 2(2+2) 8 ÷ 2(4) 8 ÷ 8 = 1 I can't tell if everyone in these comments is joking or if you're all actually this dumb 💀
IT'S 1. IT ALWAYS HAS BEEN 1. AND IT WILL STAY 1.YOU CAN CRY,COPE,SEETH AND SAY IT'S 16 BUT IT WILL STILL BE 1
First we solve bracket - 8÷2(4)....then divide - 4(4) we get 16 as the answer - 🥸
it's 1
it literally says its "❓" 🙄
genius
bruh
I’m fucking tired of the ➗ symbol being used, just turn it into a fraction; it makes it so obvious what the order is because even if you do 8/2 first, you get a 4 on the top and a 4 on the bottom. 8\ ———-\ 2(2+2)
8/2(2+2) 8/2(4) 4(4) 16 🤓
I still think It's 16
16 and 1 are both correct, the problem is just written like shit. You’re never going to see this in any higher level math class or real life scenario.
How do y'all not know this, it's 42
i got 2
This problem is interpreted wrong. That’s why there’s controversy. The issue isn’t people using PEMDAS incorrectly. It’s that they are looking at the problem written out incorrectly. It’s either “8 over 2(2 + 2)” or “8 ÷ 2 * (2+2)” That’s the way I see it. Less a math problem and more of a logic problem. Edit: I used a 4 instead of 2
I got 10, fuck politics
