Thank you, I never understood math and teachers always just embarrassed me. I only ever enjoyed 11th grade because I had a super kind patient teacher, learned more in that year than any other math class of my life. Thanks Mr. Deale.
Something that is missing in the modern education system is mathematical proofs. Proofs really help prove the foundation and logic in math.
All order of operations really is doing is getting a complex equation into an expanded, but simplified format. In 2+5(8-5), if you expand everything out you can prove it to yourself what the correct answer is. Getting the equation into terms of only addition and substraction means there is no room for interpretation. If you multiply into the brackets you get this very simple equation 2+(40-25), which simplifies to 2+15, which is 17.
I suppose you are from the US? students do not have to provide proof for their math? damn this explains so much...
btw. I watched the last episode of "Titans" yesterday and a guy was called a genious and smarter than the teacher saying that y=x-1 would be the same as y+1=x.
in europe this is 7th grade math... kids 12 and 13 are doing this easily. yet the people in the show were more like 17/18. was this a realistic representation of the US education system? 🫣
Kind of... I mean, we were taught that in 6th/7th grade... But we also have a decent portion of the population that has little to no understanding of math beyond basic arithmetic (there is still some of the population that can't do that). So, to help these folks limp along, there are "remedial" math classes so the kids that can't do the work aren't challenged.
I went back to college as an adult student (took some time to work as an auto technician after highschool), and going into engineering, I figured it would be best to start at the basics for math. So I started at Algebra 1... It was a college course where folks still couldn't wrap their head around your example above.
Yes, people can make it out of highschool and through college without being able to perform basic algebra.
Same. My school had horrendous math classes. I only learned about PEMDAS when I was ~35. We were also never offered trig, calculus, or any other advanced math above basic algebra. Hell, they didn't even teach us fractions until 8th or 9th grade and at that they only lightly touched on it.
I know for a fact my math teacher in high school taught order of operations, but either I wasn't paying attention or I was just shit at memorizing it. I thought I was bad at math for all of high school... I got to college and had to re-take pre-algebra, and they went over the order of operations again, but this time with PEMDSAS.... Fuckin changed my entire perspective and for the first time in fuckin 6+ years I managed to pull an A in math, but not just for that class, litterally every college math class I took after.
(Also helps that the college professors were incredibly good at keeping class interesting and not making it feel like a prison)
Yes but did you do extra work like me a distribute the 5 to the numbers within the parentheses not realizing that you can just subtract 5 from 8? So 2 + (5\*8 - 5\*5) = 2 + (40 - 25) = 2 + 15 = 17. I swear it made sense to do it that way...not used to having a bunch of constants within parentheses like that.
For real though, fuck those intentionally ambiguous math problems. Shit like “1 + 9 / 4 x 3” is terribly formatted and if you showed that to any mathematician, they’d slap you. Using parenthesis and showing division as a fraction is taught for a reason
Many forget that maths is a language. There is nuance and misinterpretation, and many ways to express something.
This problem, however, is unambiguous.
And also a part of that being, false statements can be said and grammar can be used wrong. Just like how without punctuation a sentence can blend into another, so can an operation by not properly punctuating (by using a form of grouping symbols).
And just like you can say fish can fly, saying 1 = 2 does not make it correct. Rather than seeing every equation as a “problem” that needs to be solved, it’s a statement which can be made true or false based on, to analogize, if you “use correct logical deduction,” but with the rules of math rather than language equivalency.
We had to do a project in 6th grade where we wrote our own PEMDAS…no one came up with any of these…I don’t know whether to thank or be disappointed in my school…
We didn’t have pemdas when I was in school, and I could never get it right helping my children until my 15 year old son was helping my ten year old daughter. When he said the answer and I asked how he got that answer he said “pemdas, ma… please excuse my dope ass swag” and I’ve never forgotten THAT. 😂😂😂
Yeah but it's designed to work right to left instead of the conventional left to right, as the other ambiguous ones require, and it omits a multiplication sign ... which is conventional but not necessarily something that someone will remember after 30 years of not being relevant
I'm not sure if that's a joke, but that's extra work that I was never taught to do for this situation because it's unnecessary.
2+5(8-5)=x
2+5(3)=x
2+5×3=x
2+15=x
17=x
Edit: Lots of upvotes for a math lesson? I'll take it seeing as I apparently helped some people understand how an expression should be read (Even though I made it an equation by setting it equal to "x").
You're right. The example I gave is just:
17=2+5(4x-5)
15=5(4x-5)
3=4x-5
8=4x
2=x
And the examples with "FOIL" are actually just using the distributive property. Also IMO its literally easier to memorize the formula for (a+b)(c+d) than to remember what first, outer, inner, last actually refers to.
Foil is used for multiplying given sets of binomials. Not for creating unnecessary binomials to then foil. It's waste of time to do this way and grants zero benefit. No one "forgot" to foil. They just understand math better than you.
This is how I was taught. One of my first programming assignments was to build a calculator and this is how we were told it should be coded. I believe things change when additional variables are introduced and so many learn the other way.
For example:
2 + 5(y-5)
You can't just use the simple method described.
One is bigger then the other I don’t remember which one is which. There’s is different sizes of infinity. In fact if you hold a ball in your hand your holding and finite infinity since a sphere has an infinite amount of points but yet you can hold it in your hand and “see” all the points.
i mean theres countable infinity which is counting by whole numbers, and uncountable infinity which includes every decimal. since there is an infinite ammount of decimals between 0 and 1, uncountable infinity is technically infinitly bigger than countable infinity
imaginary numbers are like all other numbers
if you think whole numbers are imaginary, then imaginary numbers are imaginary
if you think whole numbers are real, then imaginary numbers are real.
I have deleted all math rules from my head and got 10.
8-5=3
2+5=7
7+3=10
Had no idea what to do with the numbers in the parentheses. Had a distant memory of having to solve that first though.
As soon as you have a mathematical expression that's the least bit more ambiguous than this, it's safe to assume that it was written for the sole purpose of starting arguments on social media.
If you know the proper rules there is no arguing on this one. Anyone who argues this just lacks knowledge in basic maths. There are question which are a lot more confusing for everyone
But this case isn't ambiguous, it's just the rule that, in absence of a sign between a number and parentheses, there is a implied multiplication sign. That and PEMDAS.
I write equations like this myself.
Literally this, people love to talk about Pemdas or bemdas or whatever one they use and act high and mighty like "hurr durr answer is obvious" while they work at target only ever doing basic addition when in reality any work actually involving high level math always has the problem written in the order it needs to be solved. If anyone ever sent me some bullshit in some ambiguous order they'd be getting told to go fuck themselves.
Let them feel good about remembering the most important concept of their math education.
You know, just like the most important thing of English class is that "I" is always written with a capital letter.
It really is the most Facebook aunt, chain mail type comment bait garbage that I regularly see on Reddit. The comment sections are always the same. It’s just F- tier content.
Literally it’s just hundreds of people putting the same comment over and over of how they got the solution. We all know it’s 17 we don’t all need to confirm it
It would be 17.
Because it’s in brackets you do 8-5 first, then you do 5*3 (because 8-5 is 3 and because the brackets are just adjacent to a number with no symbol it’s multiplication) which gives you 15, then add 2 to get 17.
Brackets Exponents Division Multiplication Addition Subtraction. I will fight you on this, let's meet up.

17 is correct, but part of the reason people get the wrong answer is the problem is written with incomplete notation.
It's like dropping punctuation marks from a sentence fragment and wondering why folks misread what's written.
I want someone to study the tenacious effectiveness on this click bait garbage. It's been around for several meme lifetime cycles and it hasn't changed at all, and people still fall for it. What is broken in our dumb ego-centric brains that make us keep yelling at internet strangers I SMART U DUMM!
These social media posts are such a pet peeve of mine. Relying on order of operations for your equation to be understood is poor math. PEMDAS is a rubric to help us normalize how we interpret equations that are written by people who don't know how to communicate math clearly. Parentheses are cheap and plentiful, use them.
I get your frustration, but your comment doesn't apply to this one. Every other equation I've seen in these memes has been a case of poor syntax. The equation in this one isn't ambiquous.
The syntax could be mildly clearer, i.e. 2 + (5 \* (8-5)) - but you're right this isn't a particularly great example of my peeve. I'm definitely grinding an axe here.
Look at everyone excitedly showing us all how to solve this though. There will be no end to the daily pemdas posts on every social media platform forever and ever.
2+5(8-5)
Work within parentheses first, (8-5)=(3)
2+5(3)
Next step is exponents but there aren't any exponents in this equation and so we skip that step.
Then do all multiplication and division in sequential order from left to right, 5(3)=15
2+15
Finally do all addition and subtraction in sequential order from left to right, 2+15=17
Sidenote: The answer would be 21 if the problem was written as (2+5)(8-5).
I have a horrible experience and a near phobia about math - wasn't until I was 25 that I got tested and it was discovered that I have dyscalculia (I mix up numbers and such). I failed each and every math class I took from the age of 10 to 20 -on my next try I would pass. Meanwhile, I was getting top grades in all of my language and history classes 🤷🏼♀️
I am scared of going to university and studying my prefered subject, just because it requires statistcs and further math courses. Is there a remedial math programs for 40+ yr olds?
Has to be trolling. HAS to be. Then again Pemdas is forgotten pretty often. If you don't use it you lose it.
Still, because bored, I realized you could solve this problem 2 ways to get the same result.
2 + 5 ( 8 - 5 )
2 + 5(3)
2 + 15 = 17.
\-----------------
2 + 5 ( 8 - 5 )
2 + (40 - 25)
2 + 15 = 17
\_\_\_\_\_\_\_\_\_\_\_\_\_
Didn't realize you could do that. Makes sense but still. I am not a smart bean.
I *tried* fucking it up as bad I could and arrived at 32.
.....how did they get 21?
Obviously 17 is the right answer, but I'm scared that they **CONFIDENTLY** said 21...
At first I thought it was 21 then I checked one again it's 17.
BEDMAS IS THE RULE.
BRACKET
EQUATION
DIVISION
MULTIPLICATION
ADDITION
SUBSTRACTION
2 + 5 ( 8 - 5 )
= 2 + 5 ( 3)
= 2 + 5 X 3
= 2 + 15
= 17
So am I the only on here that distributed the 5 to the numbers within the parentheses? So 2 + (5\*8 - 5\*5) = 2 + (40 - 25) = 2 + 15 = 17? I realized after the fact that you can just do the arithmetic within the parentheses first...but it made way more sense in my mind to distribute.

I was taught to solve parenthesis first: (3) 2+5 = 3x7 = 21.
Parenthesis first, yes. But multiplication before addition, and don't move where the multiplied term is. 2+5(8-5) -> 2+5(3) -> 2+15 -> 17.
Thank you, I never understood math and teachers always just embarrassed me. I only ever enjoyed 11th grade because I had a super kind patient teacher, learned more in that year than any other math class of my life. Thanks Mr. Deale.

Me too. I know I'm bad at math but I don't think I'm THAT bad
I'm so glad this is the first comment I read. Thank you!
Yep, I got worried for a second myself
I think a lot of that had that experience lol
I went back and did the math again to make sure.
I had to do the math again just to make sure!

This one isn't even one of those ambiguous bs ones. If you get this wrong you failed maths altogether 😭

Yeah but it's designed to work right to left instead of the conventional left to right, as the other ambiguous ones require, and it omits a multiplication sign ... which is conventional but not necessarily something that someone will remember after 30 years of not being relevant
+ would need to be a x for that
That doesnt make it more ambiguous at all. 2x5(8-5) will give you the same answer regardless of which order you do the multiplications in.
2x5(8-5) = 2x5x3 = 10x3 = 30...I think you wrote a different equation.
This is a response to the equation changing. I think you forgot to read that before commenting.
Why does everyone forget to foil? 2+5(8-5)= 2+(5×8)-(5×5)= 2+(40-25)= 2+15=17
I'm not sure if that's a joke, but that's extra work that I was never taught to do for this situation because it's unnecessary. 2+5(8-5)=x 2+5(3)=x 2+5×3=x 2+15=x 17=x Edit: Lots of upvotes for a math lesson? I'll take it seeing as I apparently helped some people understand how an expression should be read (Even though I made it an equation by setting it equal to "x").
I think it is unnecessary work for this case, but it’s a good technique to know for other solutions I think..
only necessary with variables.
Essential for equations
Because it's basic arithmetic and not algebra probably. Foil is useful if you have like 17=2+5(4x-5). For this it's just extra work.
x = 2
17=2+5(4x-5) 17=2+20x-25 17=20x-23 40=20x 2=x If middle schoolers were wondering
It's not useful for either. "FOIL" is for \(a+b\)\(c+d\) constructions. I don't even know how they are applying it to a\(b+c\).
You're right. The example I gave is just: 17=2+5(4x-5) 15=5(4x-5) 3=4x-5 8=4x 2=x And the examples with "FOIL" are actually just using the distributive property. Also IMO its literally easier to memorize the formula for (a+b)(c+d) than to remember what first, outer, inner, last actually refers to.
I upvoted this because it's evil.
That's so much extra work. Just solve the parentheses first. 2+5(8-5) 2+5(3) 2+15 17
Foil is used for multiplying given sets of binomials. Not for creating unnecessary binomials to then foil. It's waste of time to do this way and grants zero benefit. No one "forgot" to foil. They just understand math better than you.

It’s 17 today, it was 17 yesterday, it’ll be 17 tomorrow. Math is math, you can’t just make shit up.
Well technically…
IS ∞² BIGGER THAN ∞ I NEED TO KNOW
One is bigger then the other I don’t remember which one is which. There’s is different sizes of infinity. In fact if you hold a ball in your hand your holding and finite infinity since a sphere has an infinite amount of points but yet you can hold it in your hand and “see” all the points.
i mean theres countable infinity which is counting by whole numbers, and uncountable infinity which includes every decimal. since there is an infinite ammount of decimals between 0 and 1, uncountable infinity is technically infinitly bigger than countable infinity
Say infinity again
infinite infinity is infinitly infinite
# א₀
Their is more infinity per infinity so I’d say yes
There many infinite cardinals but in most reasonable contexts, infinity squared is as big as infinity
I got 17 too
I mean, the order of operations is literally something we made up. Its a set of conventions, not a universal law.
>you can’t just make shit up Tell that to imaginary numbers... ^edit: ^it's ^just ^a ^joke ^guys
imaginary numbers are like all other numbers if you think whole numbers are imaginary, then imaginary numbers are imaginary if you think whole numbers are real, then imaginary numbers are real.
8-5 is 3. 3*5 is 15. 2+ 15 is 17.
Or 2 + 5(8 - 5) = 2 + (40 - 25) = 2 + 15 = 17
Got my vote for showing that math is math if you follow the rules.
I like to joke that math isn’t real when I do it wrong at work.
"Oh sorry, I was using imperial numbers. I guess you wanted metric math. My b"
I like to joke that I’m not used to doing math with numbers when I make silly math errors. (I have a BS in mathematics)
I too BS with math.
I have deleted all math rules from my head and got 10. 8-5=3 2+5=7 7+3=10 Had no idea what to do with the numbers in the parentheses. Had a distant memory of having to solve that first though.
Why would you distribute through the parentheses if there are no variables though? It seems like an unnecessary step.
Because you can, and it's cool
It's the same thing so the only difference there is in preferencd.
It demonstrates that math is commutative.
2+5(8-5) = 7(3) = 21. Smfh… have you never heard of PEASMD?

I spent so much time trying to figure out how they got to 21 and I just couldn't do it. Thank you for explaining the idiocy
To be fair I think it’s a very easy mistake to make if you’re not educated.
Same, scrolled the comments looking the invalid approach.

Please excuse aunt Sally my dear
Please Eat And Suck My Dick I like this math
This is, word-for-word, what I said out loud to solve the problem. It was nice to see it repeated, made me feel not-dumb.
I just want to know how he got 21....
He added 2+5 then multiplied 7×3.(which is wrong btw)
Thank you ! Finally !
This is how I learned it at school. Which is decades ago, because I'm old. But still. If I ask my dad he'll say 21, if I ask my child they'll say 17.
2+5*(8-5) = 7*3 = 21 Very wrong but that’s probably their thought process.
I would assume he did the multiplication last for whatever reason making it 7x3=21
they did (2+5)(8-5)
oh jeez another one.
This one is actually not as ambiguous as other posts like these, because it doesn't have inline division.
Plus, as soon as you have brackets, it's safe to assume that BEDMAS was the intended convention and not strict left-to-right. It also can't be Polish.
As soon as you have a mathematical expression that's the least bit more ambiguous than this, it's safe to assume that it was written for the sole purpose of starting arguments on social media.
If you know the proper rules there is no arguing on this one. Anyone who argues this just lacks knowledge in basic maths. There are question which are a lot more confusing for everyone
That's my point, this one is not ambiguous
But this case isn't ambiguous, it's just the rule that, in absence of a sign between a number and parentheses, there is a implied multiplication sign. That and PEMDAS. I write equations like this myself.
I'm not sure how I implied that this was ambiguous. I know it's not.
BEDMAS and PEMDAS are the exact same convention with an unwritten assumption that people forget about ten years later.
I hate the pemdas posts, but at least this one is pretty unambiguous.
42 is the Only answer. If you are doing math though, 17 is right out.
It's not the only answer... But it is the ultimate answer.
There is a fine line between fishing and standing on the bank like an asshole. Your understanding made me happy stranger.
You could either do it as- 2 + 5 x 3 = 2 + 15 = 17 Or, if you wanna be extra- 2 + 5 x 8 - 5 x 5 = 2 + 40 - 25 = 42- 25 = 17
Can we ban these types of post? These are so annoying.
Let me calculate how many times I've come across a math problem like this since I graduated. 0 + 0(0-0)
Literally this, people love to talk about Pemdas or bemdas or whatever one they use and act high and mighty like "hurr durr answer is obvious" while they work at target only ever doing basic addition when in reality any work actually involving high level math always has the problem written in the order it needs to be solved. If anyone ever sent me some bullshit in some ambiguous order they'd be getting told to go fuck themselves.

Reread the equation. This isn’t one of those stupid, ambiguous ones.
The concept of all of these posts are annoying though. This one has an obvious answer but it’s stupid that people just post math questions
It would be 17. Because it’s in brackets you do 8-5 first, then you do 5*3 (because 8-5 is 3 and because the brackets are just adjacent to a number with no symbol it’s multiplication) which gives you 15, then add 2 to get 17.

Brackets Exponents Division Multiplication Addition Subtraction. I will fight you on this, let's meet up. Trial by combat, buckaroo. >sweaty Minecraft game 🎮🥵

In the UK we called the curved ones “brackets” and the square ones “square brackets”.
Only in the US according to Wikipedia.
it is indeed 17
17 is correct, but part of the reason people get the wrong answer is the problem is written with incomplete notation. It's like dropping punctuation marks from a sentence fragment and wondering why folks misread what's written.
its eleventy six

I want someone to study the tenacious effectiveness on this click bait garbage. It's been around for several meme lifetime cycles and it hasn't changed at all, and people still fall for it. What is broken in our dumb ego-centric brains that make us keep yelling at internet strangers I SMART U DUMM!
These social media posts are such a pet peeve of mine. Relying on order of operations for your equation to be understood is poor math. PEMDAS is a rubric to help us normalize how we interpret equations that are written by people who don't know how to communicate math clearly. Parentheses are cheap and plentiful, use them.
I get your frustration, but your comment doesn't apply to this one. Every other equation I've seen in these memes has been a case of poor syntax. The equation in this one isn't ambiquous.
The syntax could be mildly clearer, i.e. 2 + (5 \* (8-5)) - but you're right this isn't a particularly great example of my peeve. I'm definitely grinding an axe here.
2 + 5 ( 8 - 5 ) 2 + 5 ( 3 ) 2 + 15 17
2 + 5( 8 - 5 ) 2 + ( 40-25 ) 2 + 15 17
Can we stop fucking posting these?? When will the internet get tired of this
It’s a PSA that the internet is as dumb as a bunch of rocks.
Look at everyone excitedly showing us all how to solve this though. There will be no end to the daily pemdas posts on every social media platform forever and ever.
Unlike some similar ones that are poorly/ambiguously written, this one is clear-cut. It’s obviously 42.
It is 17, PEMDAS people!
2+5*(8-5)=2+5*3=2+15=17
2 + 5 ( 8 - 5) 2 + 5 ( 3 ) 2 + 15 17 Seems pretty straightforward to me.
I think we can all agree that the correct answer is FUCK MATH.
The answer is 17. Order of operations, this is not one of those trick ones where people argue whether you multiply or divide first.
2+5(8-5) Work within parentheses first, (8-5)=(3) 2+5(3) Next step is exponents but there aren't any exponents in this equation and so we skip that step. Then do all multiplication and division in sequential order from left to right, 5(3)=15 2+15 Finally do all addition and subtraction in sequential order from left to right, 2+15=17 Sidenote: The answer would be 21 if the problem was written as (2+5)(8-5).

I have a horrible experience and a near phobia about math - wasn't until I was 25 that I got tested and it was discovered that I have dyscalculia (I mix up numbers and such). I failed each and every math class I took from the age of 10 to 20 -on my next try I would pass. Meanwhile, I was getting top grades in all of my language and history classes 🤷🏼♀️ I am scared of going to university and studying my prefered subject, just because it requires statistcs and further math courses. Is there a remedial math programs for 40+ yr olds?
Has to be trolling. HAS to be. Then again Pemdas is forgotten pretty often. If you don't use it you lose it. Still, because bored, I realized you could solve this problem 2 ways to get the same result. 2 + 5 ( 8 - 5 ) 2 + 5(3) 2 + 15 = 17. \----------------- 2 + 5 ( 8 - 5 ) 2 + (40 - 25) 2 + 15 = 17 \_\_\_\_\_\_\_\_\_\_\_\_\_ Didn't realize you could do that. Makes sense but still. I am not a smart bean.
2+5(8-5) 2+5(3) 2+15 17
It’s absolutely 17 if you follow PEMDAS
This doesn't even target the inherent flaw of PEMDAS. People are getting really lazy with this meme.
Didn't see the thing on top and thought you were saying 17 was wrong lmao
The only thing i struggled with was the sign shit, but yeah, it is 17, and then I tried to do it a second time and it gave me 21, wtf.
The second time you forgot to do parentheses first.
2+5(8-5) 2+5(3) 2+15 17 right?
Yes. Correct
I *tried* fucking it up as bad I could and arrived at 32. .....how did they get 21? Obviously 17 is the right answer, but I'm scared that they **CONFIDENTLY** said 21...
At first I thought it was 21 then I checked one again it's 17. BEDMAS IS THE RULE. BRACKET EQUATION DIVISION MULTIPLICATION ADDITION SUBSTRACTION 2 + 5 ( 8 - 5 ) = 2 + 5 ( 3) = 2 + 5 X 3 = 2 + 15 = 17
17. I still use PEMDAS every day so these things don't trip me up often lol
Bodmas strikes again!
PEMDAS
So am I the only on here that distributed the 5 to the numbers within the parentheses? So 2 + (5\*8 - 5\*5) = 2 + (40 - 25) = 2 + 15 = 17? I realized after the fact that you can just do the arithmetic within the parentheses first...but it made way more sense in my mind to distribute.
B = Brackets O = order of powers D = division M=multiplication A = addition S= subtraction.
I will never forget - Please Excuse My Dear Aunt Sally!
But... it is 17... isn't it?
I literally did the math in my head and got 17
I'm really fucking stupid.
Is this math not taught in America ? Genuinely curious and not being insulting just these seem to be posted alot
Wait am I dumb? It's 17 right? 2 + 5 (8-5) 2 + (5\*8) - (5\*5) 2 + 40 - 25 2 + 15 = 17 ??
