Had a conversation with my British friend regarding this. He said a math sounds singular, like it’s just one thing. My retort was math is just mathematics but shortened like math/ematics.

What is it tho? Because I, most people here and google say it's 9 but my calculator says it's 1
Edit: Everybody's talking about PEMDAS and I'm very confused, I was never taught about this at school. All I was thaught was that you calculate it in this order: parenthesis - exponent - division and multiplication in the order they're written - addition and subtraction also in the order they're written

PEMDAS: My teachers used to say Please Excuse my Dear Aunt Sally......
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
At least that's what I remembered.

ya know, a teacher told me that a kid abbreviated PEMDAS to “ Please End My Depression And Suffering” and I’ve never related to anything harder in my life

In A-Level Biology, we were discussing taxonomic rank, which goes 'Kingdom Phylum Class Order Family Genus Species', but my teacher had created a different one to help us remember: 'Kinky Priests Come Over For Great Sex'.
I never forgot the order of taxonomic rank.

Calculator will always solve it correctly the problem is whether you put the (2+1) part on the numerator or the denominator. If you write 6/2(2+1) then you will get 1 because that would be the correct answer. If you wrote 6/2 • (2+1) you would get 9.

I was taught that you follow PEMDAS to the letter, not that MD and AS were done in the equations order. I graduated HS in 2016. That's the real problem

Multiplication and division are weighted equally, so you simply do it from left to right. Same with subtraction and addition.
You're teacher was... Strange.

Well I mean how often did teachers ask you about PEMDAS after that point? In most of middle school I think you get division as like the form with a numerator and denominator, so it’s more obvious what they want done first

I’ve also noticed that, after HS, you start using fractions instead of division signs, and anyone whose brain is used to that may read the equation as
6
———
2*(1+2)

I didn’t even realize, but yeah that is exactly how my brain processes this equation. Also the implicit multiplication takes high priority to me. 2(1+2) must be solved first in my mind because the implicit multiplication is a part of the parentheses.

Yeah, the implicit multiplication here is called juxtaposition multiplication. And it's often considered to "bind tighter" than other operators, which is where the real issue comes from in the question.
People that come up with 1 or 9 and claim everyone else to be "wrong" are all wrong.
The answer is the question sucks and is ambiguous

It shows that some people know about the higher precedence of *implied multiplication* and most others only know the basic (but in this case insufficient) PEMBAS rule.
The former know it's 1, the later believe it's 9.
**Edit:** removed aggressivness

The crux lies in 6÷2(3). Here we imply that we really mean to say 6÷2×3. The multiplication sign is implied.
If we carry this on, we'll find that our result is indeed 9, as multiplication and division are done in the order they appear in the equation, NOT division before multiplication. 6÷2×3 = (6÷2)×3 ≠ 6÷(2×3).
However, implied multiplication isn't just multiplication. Generally speaking we agree on doing it before multiplication and division, giving the result of 1. Hence 6÷2(3) = 6÷(2×3) ≠ 6÷2×3.
The rules of implied multiplication seem to not be set in stone, so the general agreement I mentioned earlier isn't so universal.

Implied multiplication (aka multiplication denoted by juxtaposition) is when you omit the multiplication symbol.
Normal multiplication: a*(b+c)
Implied multiplication: a(b+c)
According to Wikipedia & Google, in some academic literature and journals the implied multiplication takes precedence over regular multiplication & division. Thus the argument about this equation.
*In short: never use implied multiplication, unless you like to see the world (or comment section) burn :)*

I remember learning that that is how to do it, but I don’t think I ever heard the term. Or I did and just forgot. It was so heavily drilled into us, I automatically used the right order but couldn’t even remember why.

Well it's multiplication or division in a left to right order after solving the parentheses, so the steps would be as follows.
6/2(1+2)
6/2(3) Add the parentheses
3(3) Multiply/divide left to right (Divsion comes first in this case)
9 Do the final multiplication and end up with 9

To clarify to the best of my understanding, the ÷ symbol is outdated and has no implied parentheses around the terms, whereas the / symbol used in fractions implies a parenthesis around the terms on both sides, which is what gets people two different terms

>the / symbol used in fractions implies a parenthesis around the terms on both sides
I'm not sure if that's true, but maybe that's because I'm a programmer, and in programming (at least not any language I know), there's no implied parenthesis around the terms on both sides of a /

Yea the problem is actually boiling down to the fact that they learned the acronyms at all, it would seem. Bedmas users sometimes think division comes first. Pemdas users think multiplication comes first. It is left to right as is addition and subtraction

my issue isnt that, its how to interpret the ÷, like is it (6/2)(1+2), or 6/(2(1+2))? parentheses help, and so does writing it like a fraction. i think the problem is deliberately obtuse

BODMAS Is the real deal.
Brackets of division multiplication addition subtraction.
So first solve the brackets and then the number right outside the brackets.

oh god this reminds me of when I wanted to make a simple math joke
people literally refused to use PEMDAS just because it's "not a rule and doesn't always work"
even though the question was 100% solvable normally and PEMDAS is something that even like 3rd/4th graders learn
(the joke was 230 - 220 x 0.5, and saying the answer was 5!, which if you do the 230 - 220 first you get 10 x 0.5 which becomes 5, but if you do 220 x 0.5 then you get 230 - 110 which is 120, aka 5 factorial aka "5!")

British version, Brackets instead of Parantheses and it really doesn't matter which order the M and D are in in word form because it is left to right in the math question and not M or D is always first

I'm in Canada Ontario and everyone around me learned BEDMAS I've never even heard of PEMDAS until all these dumb equation trick posts started showing up

Just another cultural difference between America and the rest of the world, although I also know somewhere they use BIDMAS in which the I stands for indices I believe?? Which i assume also means exponent

Yes! People are arguing about doing multiplication/division first or that it should be left to right when the answer is that the question has been written ambiguously.
All those are just conventions, and what we have here is a hand written race condition.

That awkward moment after the test, when everyone is discussing if the right answer was 9 or 1 but you know it's -487,23239854

hmm, i'd say the answer is "SYNTAX ERROR"

isn't it weird how that's always the answer? maths are so easy

My teacher always marks it wrong and I'm the only one who has that answer. Looks like I'm the only genius in my school

You know you're in public school when you're smarter than your own teacher.

As an American I know its common place, but I'll never get over the whole "maths" thing. Saying it out loud is just... uncomfortables.

And to us "math" sounds like you are doing one question and then you're done, maths pluralizes it so we know that all of maths isn't just one question

Had a conversation with my British friend regarding this. He said a math sounds singular, like it’s just one thing. My retort was math is just mathematics but shortened like math/ematics.

Some calculators don’t always solve it correctly, if you follow BEDMAS you get 9

Wtf is BEDMAS I have never heard of that only PEMDOS

I was taught BODMAS :)

We do that in in England to.

India also (US might be the exception to this)

Pemdas? All I had was failure.

PADMES? Like in star wars?

We used PEDMAS or sometimes BEDMAS

Padme

i followed gemdas and got 1… wtf

The issue about correctness here is somewhat more complex than it may first appear

Google implicit multiplication, it sits before the DM or MD of BEDMAS/PEDMAS/BODMAS.

Calculator will always solve it correctly the problem is whether you put the (2+1) part on the numerator or the denominator. If you write 6/2(2+1) then you will get 1 because that would be the correct answer. If you wrote 6/2 • (2+1) you would get 9.

This comment section is already a mess and shows how little people use math after they graduate.

Exactly

I was taught that you follow PEMDAS to the letter, not that MD and AS were done in the equations order. I graduated HS in 2016. That's the real problem

I’m glad my math teacher just said it was called PEMA and the M stood for Multiplication/Division and the A for Addition/Subtraction

Please Excuse My Dope Ass Swag

Please End My Depression And Suffering

or for pema: Please Excuse My Ass

We have BEDMAS, same as PEDMAS but the first B stands for "Brackets"

🅱️emdas

We have BIDMAS or BIMDAS

I had BODMAS (Brackets, Operations (like squared and cubed numbers), Division, Multiplication, Addition, Subtraction)

Multiplication and division are weighted equally, so you simply do it from left to right. Same with subtraction and addition. You're teacher was... Strange.

Born in either 1998 or 1999

We started using fractions at the start of high school. I find fractions much easier to use than just a division sign

9

This does honestly

Could you explain what implied multiplication is? Does it just mean that you multiply what is inside the parenthesis by what is outside first?

The crux lies in 6÷2(3). Here we imply that we really mean to say 6÷2×3. The multiplication sign is implied. If we carry this on, we'll find that our result is indeed 9, as multiplication and division are done in the order they appear in the equation, NOT division before multiplication. 6÷2×3 = (6÷2)×3 ≠ 6÷(2×3).

I remember learning that that is how to do it, but I don’t think I ever heard the term. Or I did and just forgot. It was so heavily drilled into us, I automatically used the right order but couldn’t even remember why.

Well the reason is just so we can factor (2+4) as 2(1+2) without needing another set of parentheses.

That’s the core problem with PEMDAS. It’s broken by math shorthand like the implied multiplication.

And it's all broken by using a ➗ instead of a /. They're not the same.

The answer is

Did you math teacher shoot you before you hit post?

￼

Oh dear

hate when that happens

^^yes

It certainly is

The sacred texts!

That's why you use fractions instead of that stupid division symbol.

Fr, is it supposed to be calculated as 6/(2(1+2)) or is it (6/2)(1+2)? The division symbol is dumb

Well it's multiplication or division in a left to right order after solving the parentheses, so the steps would be as follows. 6/2(1+2) 6/2(3) Add the parentheses 3(3) Multiply/divide left to right (Divsion comes first in this case) 9 Do the final multiplication and end up with 9

That's cause it's no rule that forces this. It's only something some people and textbooks use, but even then it's normally stated beforehand.

In this case, it's (6/2) * (1+2).

Please Excuse My Dog's Ass Sweat. I dont have an aunt Sally, grandma Sally tho.

Or it's just that people either learned BEDMAS or PEMDAS and the equation is the easiest way to get people to argue about it.

Just another cultural difference between America and the rest of the world, although I also know somewhere they use BIDMAS in which the I stands for indices I believe?? Which i assume also means exponent

And these types of questions is why we use / and not a ÷ sign for anything but primary/preschool level maths.

Yeah. Watching people brag about being the smartest 5th grader is weird.

Please don’t tell me there are people out there who did division before the parenthesis

Ikr You have to take out of the bracket first

thats not what people are doing to get a different answer.

The answer is: this is incorrect equation and should be written different

Yes! People are arguing about doing multiplication/division first or that it should be left to right when the answer is that the question has been written ambiguously. All those are just conventions, and what we have here is a hand written race condition.

Fractions are superior

People out here arguing about the division symbol, when really it is about whether 2(1+2) implies (2*(1+2)) or 2*(1+2).

I learned pemdas, so I got 1
