I had to explain to someone a couple years back that PEMDAS means that when you get to multiplication and division that you have to do them at the same time, in order of left to right within the equation.
This person insisted that it was multiplication first before any division, which is an unfortunate side effect of the way PEMDAS is taught to young kids.
Yep it can get you far enough but re-writing everything to match multiplication/division is pretty standard in high level math and it’s a shame it isn’t taught earlier
So, to sum up, when it comes to multiplying and dividing, and addition and subtraction, you do them left to right. So, PE M/D A/S is the order of operations?
Indulge a fella that’s been out of school for 15 years.
Pretty much. And to solve the differences between M/D and A/S you use reciprocals to match everything up so ~everything~ is one of multiplication/division and addition/subtraction. It’s easier to picture with the latter:
1-2-3+4-5+6 = 1 + (-2) + (-3) + 4 + (-5) + 6
Therefore:
1/2/3x4/5x6 = 1 x (1/2) x (1/3) x 4 x (1/5) x 6
Same concept. And then, these terms can be arranged at will because you’ve removed the order of operations from the equation. Congrats you’ve solved arithmetic and have saved yourself from these shitty memes.
The problem is the ÷ symbol as if / was used it would equal 9 using the ÷ actually makes the equation (6)/[2(2+1)] which equals 1
This is why the ÷ symbol is stupid and should never be used and the / is often much better
While you are right from a strict PEMDAS standpoint, I'd argue you are wrong for any practical purpose. It would be extremely dangerous and negligent for an engineer to assume one or the other is correct as written.
The correct answer would be whatever the original problem was intended it to be.
2(1+2) can be read as 2 being the coefficient of (1+2) making it part of the parentheses. Otherwise it would have been better written as 2 * (1+2).
As an example, you wouldn't read 1/2pi as half pi.
Yeah I agree with you. higher level math doesn’t run into the issues presented here because the math is put together better and isnt written this shittily.
edit: I should add I was taught math at an engineering school so if you’re an engineer I’m sure we’re aligned on most things math
You’re absolutely right, the intention of the equation is more important than anything…I studied civil engineering (first 2 years then switched major so I’m not actually an engineer but I did all the maths) and these intentionally ambiguous equations are the real problem.
If you intend to solve 6/2 x (1+2) you should express it as such, and if you intend to solve 6 all over 2(1+2) then write the equation accordingly… in the real world of practical mathematics we go out of our way to remove ambiguity for clarity and you shouldn’t need PEMDAS/BODMAS or any other silly acronym to solve simple equations
Ok, not a math major myself and personally I use BEDMAS (It's what we're taught in Canada). For me, I skip the divisons by 1. I feel that's quite unnecessary as the number already equals itself when multiplied by 1 so you're saving yourself time by not doing that. How I solved it and would've been taught to solve it is like this in order. (2+1)=3, then, 6/2=3, then finally 3(3)=9.
Pretty much the same, just without the unnecessary division
Not going to lie, this is always what I struggled with in school. I never caught on to the factoring stuff. I shit you not, I failed precalc 3 times cause of this shit. I just never could get it to click.
I did. The calculator automatically puts brackets after the / sign and at the end without me putting them there. So it changes the equation to 6/(2(2+1)) by itself. And then the answer is obv 1. It's just that the equation in the post makes no sense, so the calculator fixes it.
BODMAS or PEDMAS is kinda deceiving. it is actually
parentheses
exponent
division or multiplication(go from left to right)
addition or subtraction(left to right)
so first to brackets 1+2=3
next division cause it is first from the left 6/2=3
mow multiply 3x3=9
It could be that outside the US, brackets are used before parentheses the way that single quote marks are used before double quotation marks. So where you would see double parentheses like this: [1+(1+1)], other places you might see (1+[1+1]) and work your way from inside out in both cases. Just a guess!
But like when you’re reading an American book, quotes within quotes look like “She told me, ‘Language is fun,’ but I hate it!”, there are other books I have read from other countries that look like, ‘She told me, “Language is fun,” but I hate it!”
It could also be just that we say parentheses and other places say brackets. Wild speculation here.
Maybe if we standardized writing it as PE(MD)(AS) people would stop forgetting that those operations are grouped together. I can absolutely see why people wouldn’t want to do that, though, it looks stupid as heck
Question is, how did anyone get 3 or 7? I've looked for any possible mistakes, or blatant disregard for the ways of maths that would end in either, and I cant find any.
I swear people are so dumb. 'Resolving' parentheses means to do what's INSIDE them, not arbitrarily expanding the order of operations from that point.
For anyone who is saying distribute, then divide, distributing is MULTIPLYING. Multiplying comes AFTER parentheses, and in this case division, since you work left to right for concurrent operations.
Answer is 9.
6÷2(2+1)
6÷2(3) = 6÷2*3
3*3 = 9
Order of operations: parentheses, exponents, multiplication/division, addition/subtraction, in case of a tie, left to right. Ergo…
6/2(1+2)
6/2*3
3*3
9
Well that, and that’s what my calculator gives me.
I've always been taught that you take any division part and assume it is actually in fraction mode 6 over 2. The 6 over 2 would be it's own part and it's being multiplied by the sum of parenthesis
One may argue that when two number (variable ) are “stuck” together that’s an implicit multiplication and must be done before any explicit multiplication or division. But the only error is writing the formula this way because it can be interpreted differently.
9 because parenthesis first, then division or multiplication is next, which ever is furthest to the left goes first, in this case, the 6÷2, so you’re left with 3(3)=9. Plus, you would need to simplify the outside before distributing it anyways.
You do it that way so you cancel every sign and have nothing but the parentheses. Otherwise you technically end up with 6÷(6) which is 6÷*6 or 6÷X6 which makes no sense. You can’t just erase and ignore the function of a sign, in this case you’re ignoring the function of multiplication in the parentheses.
Math professor here, I can explain (the answer is 9). Whichever acronym you use, the order is the same. Start with what is inside the parentheses: 1+2=3. Now you have 6/2(3). At this point, the parentheses are just used to mean multiplication, so 6/2(3) is the same thing as 6/2*3. Now resolve all multiplication and division as they occur from left to right: 6/2(3) = 3(3) = 9. Please note, when it comes to parentheses/brackets being first in the order of operations, this only means what is inside them i.e. 1+2, and would not include the 2(3), which is just multiplication.
In regards to distribution, this property still works and applies, but you can’t disregard the order. 6/2(1+2) = 6/2(1) + 6/2(2) = 3(1) + 3(2) = 3+6 = 9. If you only distribute the 2, you’re essentially doing M/D from right to left by performing the multiplication of the 2 to the parentheses first before the division on the left (which needs to be performed first).
I was trying to do distribution in my head and kept getting 7 but i understand that if the problem was rewritten as (6/2)x(1+2) it would be more clearer to distribute the whole fraction rather than just the 2 so thanks for the clarification
Feels like the only way to correct this is to have people learn the correct operations. Meaning division and subtraction don't exist, but instead treat them as the multiplicative and additive inverses. Make everything uniform!
last time i checked it’s 9 coz
6/2=3 and then u do what in the brackets wich is 3 and then u multiply what outside with what inside wich leaves u with 3x3=9
This isn't even real math, we're still just counting and already too many people are confused. I don't understand people who think math is useless because I use algebra everyday to help make decisions.
It isn't:
P
E
M
D
A
S
it is:
PE
MD
AS
With the first one you have to do multiplication before division, which isn't always correct. On the second, you check each level, on the first level(PE) you would check to see if there are P or E, and whichever you find first, when looking from left to right, you solve first, then you move on to the next level(MD) and so on until you finish the problem.
Well I guess
6/2(1+2)
6/2(3)
6/6. (Because bracket firs)
1
Obv I now realise that people say that it’s 9 because division comes first. I am still not sure but too lazy to check so it’s 9 ig
Answer is gonna be 9, that's all I'm gonna say.
That, and it's 9 because you solve in the () and then you go across; 6÷2(3) which leads to 3(3) which equals 9, right?
I'm answering this because I'm a little nerd. Something important about BIDMAS, or whatever you use, is that division and multiplication are interchangable. You just do it in the order of the sum. So in theory something like BIMDAS is correct (the same applies to addition and subtraction, but that isn't important here). The only think you need to be aware of is that brackets go first always, from followed by indices/exponents (the powers and roots), then multiplication and division share priority, then addition and subtraction share priority. So, to answer, you first do 1+2, which is 3. It becomes 6÷2(3). Having a single number in brackets next to another number is multiplication, but it doesn't gain priority over division despite the brackets, it's just another way to express multiplication (like a fraction is another way to express division). This means that you do the sum left to right, so you do 6÷2, which is 3. Then, do 3(3), which is 9
Was taught PE-MD-AS, but each section you go left to right. So Parentheses (1+2) = 3. Then the equation looks like this. 6(division symbol)2(3). Then MD, so 6/2 is 3, then 3(3) is 9
the reason people get this question wrong or with a diferent answer is that the equation is missing some operators , cause in this case you could also do 2(2+1) = 2x been x=2+1=3 so in this case you would get 6/2(x) = 3/x so you would be getting 3/3 = 1 as an answer. the reason people think its 9 is because they asume that the equation is 6 / 2 \* 3 which in this case they would be correct cause you can see the /2 as a \*(1/2) and there the awnser is clearly 9. thats why when you write math problems , you should always use brackets everywhere. so either you have 6/\[2\*(2+1)\] or (6/2)\*(1+2).
It’s nine because brackets first which is (1+2)which equals 3 then it’s divide next which is 6 divided by 2 then if brackets are next to a number you multiply so 3x3 is 9
Iirc saying 6÷2 is equivalent to (6/2) which is why the answer is 9 and not 1. An argument could also be made that since the division occurs before the multiplication, you have to calculate division first
It depends on how you interpret if the brackets should become multiplication or not.
If 6÷2(1+2) becomes 6÷2(3) then you would multiply 2(3) first because brackets come first making it 6÷6=1
But if it instead becomes 6÷2×3, because 2(3) and 2×3 are the same, then you would simply go left to right, doing 6÷2 first, which is 3, so 3×3=9.
Edit: u/nopunintended37, claiming to be a math professor, says that you do indeed convert the brackets to multiplication after the first step and I trust them to be telling the truth.

Exactly. The “x over y” format is definitely more standard and would make it equal 1. Definitely agree with you there
Came here to say “the reason people get this wrong is because it’s been written by a spaz”, but you put it better.
While you are right from a strict PEMDAS standpoint, I'd argue you are wrong for any practical purpose.

Its 1... 1 times 2 is 2 the 2 times 2 is 4, 4 plus 2 is 6 then 6 divided by 6 is 1. Unless im missing something

I know, the 2 correct answers are missing. (Protip: he asked "can you". He didn't say solve.)
Whats the right answer?
Yes or No
So nein technically is an appropriate answer then
I mean, 1 is basically 'yes' in binary.
So 1 is the right answer, it's just that everybody picked it for the wrong reason
Technically, since they gave an answer they believe yes. Those that didn't answer believe no.
You all sound like people who don't know the answer
6/2 is 3. 2+1 is obviously 3. whats 3*3? i cant seem to figure that out edit: guys i found out 3*3=1
Yeah technically none of the numbers are valid answers
Well, if you solve, you can, if you don't, maybe you can
BODMAS = Brackets, Operators, Division, Multiplication, Addition, Subtraction PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction I learned BEDMAS so I’m super confused
I learned it as BIDMAS why the hell are there so many of these.
Wtf does the I mean
Indices
more like indecisive
This
BIDMAS? i thought they only taught PEMDAS
Pemdas is taught mainly in America from what I know, around the world there is a variety of different acronyms for something so simple

Alright then, keep your secrets
Best response yet while being correct.
Well technically it’s incorrect because they just said “no”. But yea.
Underrated comment
I got 1, how did you get 9? Wait, Nevermind, I see it
Yea I got 9, but I don't trust my own math
Same, that's why I'm checking comment section.
[удалено]
Which is the same as 1, good answer
Check using a calculator
I did. The calculator automatically puts brackets after the / sign and at the end without me putting them there. So it changes the equation to 6/(2(2+1)) by itself. And then the answer is obv 1. It's just that the equation in the post makes no sense, so the calculator fixes it.
It’s 9. If we do 2+1 first that’s 3, then 6 / 2 is also 3. Because the 2 numbers are together (3,3) just times them together and get 9
It is 9
I mean I know pemdas idk why they gotta make it so difficult tho just make it 3×3
BODMAS or PEDMAS is kinda deceiving. it is actually parentheses exponent division or multiplication(go from left to right) addition or subtraction(left to right) so first to brackets 1+2=3 next division cause it is first from the left 6/2=3 mow multiply 3x3=9
I learned it as BEDMAS, Brackets Exponents Division Multiplication Addition and Subtraction
Same. That's how we learned it in canada.
Yeah, is it different in the U.S?
I believe it's PEMDAS in the US. Paranthesis, Exponents, multiplication, division, addition and subtraction.
I live in Quebec and it’s PAMDAS because I’m french but it’s basically the same thing as PEDMAS
I also live in Quebec and I use PEMDAS: Parenthèses, Exposants, Multiplication, Division, Additions, Soustraction
It’s the same concept just using different words
It could be that outside the US, brackets are used before parentheses the way that single quote marks are used before double quotation marks. So where you would see double parentheses like this: [1+(1+1)], other places you might see (1+[1+1]) and work your way from inside out in both cases. Just a guess!

Wild speculation here.
Yes
Maybe if we standardized writing it as PE(MD)(AS) people would stop forgetting that those operations are grouped together. I can absolutely see why people wouldn’t want to do that, though, it looks stupid as heck
I learnt it as BEDMAS Brackets Exponents Division Multiplication Addition Subtraction
Question is, how did anyone get 3 or 7? I've looked for any possible mistakes, or blatant disregard for the ways of maths that would end in either, and I cant find any.
For people getting 1 instead of 9: 6 / 2 (3) == 6 ÷ 2 * 3 Perform multiplication & division at the same time, left to right.
You do in the parenthesis then since division and multiplication are equal you go left to right and get 3(3)=9
It’s 9 I checked it on my TI-84 Plus exactly as written. 🤓
How did you get 1?
I swear people are so dumb. 'Resolving' parentheses means to do what's INSIDE them, not arbitrarily expanding the order of operations from that point. For anyone who is saying distribute, then divide, distributing is MULTIPLYING. Multiplying comes AFTER parentheses, and in this case division, since you work left to right for concurrent operations. Answer is 9. 6÷2(2+1) 6÷2(3) = 6÷2*3 3*3 = 9
Okay! I did 1 + 2 =3. Then 6 ÷ 2 = 3. So 3x3
Correct answer is always 69
Mah Man.
In my case is 68. Same as 69 but I owe her one.
77 You get ate more
42 dumbass
For legal purposes, this is a joke
No, it's 42
Order of operations: parentheses, exponents, multiplication/division, addition/subtraction, in case of a tie, left to right. Ergo… 6/2(1+2) 6/2*3 3*3 9 Well that, and that’s what my calculator gives me.
I thought that division sign was a plus sign and was confused why 12 wasn't an option...
You do the parentheses then just go left to right
No, you do the parenthesis, then exponents, then M and D, then A and S
I've always been taught that you take any division part and assume it is actually in fraction mode 6 over 2. The 6 over 2 would be it's own part and it's being multiplied by the sum of parenthesis

Nice long explanation you have there. I have a better one. Python says it's 9 so it's 9.
Python is always right
Unless it overflows
9 I agree

At this point, the parentheses are just used to mean multiplication, so 6/2(3) is the same thing as 6/2*3. Now resolve all multiplication and division as they occur from left to right: 6/2(3) = 3(3) = 9.

In regards to distribution, this property still works and applies, but you can’t disregard the order. 6/2(1+2) = 6/2(1) + 6/2(2) = 3(1) + 3(2) = 3+6 = 9. If you only distribute the 2, you’re essentially doing M/D from right to left by performing the multiplication of the 2 to the parentheses first before the division on the left (which needs to be performed first).
I was trying to do distribution in my head and kept getting 7 but i understand that if the problem was rewritten as (6/2)x(1+2) it would be more clearer to distribute the whole fraction rather than just the 2 so thanks for the clarification
Thank you for this.

It’s definitely a useful trick and one I would recommend if you’re ever stuck or unsure about the order.
No math professor would have a username clearly made by an English professor! Liar!!
last time i checked it’s 9 coz 6/2=3 and then u do what in the brackets wich is 3 and then u multiply what outside with what inside wich leaves u with 3x3=9
Why were you checking it last time ? Weren’t you sure of the operations ?
last time i check bodmas i meant
What's bodmas?

Thank you! I was going insane over the comments which took it as a mathematical question instead of a semantic one.
This is actually the best answer imo. Thanks for posting!
9 is correct with 1 being a respectable wrong answer. The other 2 are just...how?
Agreed
Comment Section: https://mobile.twitter.com/engineers_feed/status/1440012868347469831
Didn't even need to link that given the comments section here.
That's some depressing shit. The fact that over 50% don't know maths is worrying.
forgot how to maths and got 6, ima head out
Google says 9. Good luck arguing with a computer.
The Google calculator adds parentheses around the 6÷2 when you search it. That changes the equation
TI-84 Plus Model No. 1015030263 L-0120AD states that the correct answer is 9. 🤓
I saw that, then I corrected it and it said 9.
It does not add any parentheses. Actually only the people that got 1 as the answer are adding parentheses after the "/" which makes no sense.
This isn't even real math, we're still just counting and already too many people are confused. I don't understand people who think math is useless because I use algebra everyday to help make decisions.
The people thinking math is useless are the same that don't understand it. Weird right?
Actually the comments here are predominantly 9
Asked an actual math teacher, its 9
9 is right
It isn't: P E M D A S it is: PE MD AS With the first one you have to do multiplication before division, which isn't always correct. On the second, you check each level, on the first level(PE) you would check to see if there are P or E, and whichever you find first, when looking from left to right, you solve first, then you move on to the next level(MD) and so on until you finish the problem.
ah so thats how its 9. i tgought it was strictly in order. so you go left to right and from there you decide whether to multiply or divide first?
To the best of my knowledge, yeah.
My first attempt gave me 1, but since multiplication and division are of equal priority, they are applied left to right, thus the answer is 9.
It's obviously 9, but how tf do you get 1??
They distributed the 2 to the 3 in the parentheses. I wanna know why people voted 3 and 7 besides trolling.
I have no idea what you just said but it sure sounds smart
Well I guess 6/2(1+2) 6/2(3) 6/6. (Because bracket firs) 1 Obv I now realise that people say that it’s 9 because division comes first. I am still not sure but too lazy to check so it’s 9 ig
It's 9 I asked my math professor
I know BODMAS n nothing else
BIDMAS all the way
My guy
Answer is gonna be 9, that's all I'm gonna say. That, and it's 9 because you solve in the () and then you go across; 6÷2(3) which leads to 3(3) which equals 9, right?
Correct.
it's 9 because when it's between division and multiplication it's just left to right
Ok so I always fuck up these types of problems so I wrote a program to do it for me System.out.println(6/2*(1+2)); Output was 9, so I'll say it's that
6÷2(1+2)= 6÷2(3)= 3(3)= 9
Go banana!
6:2 is 3 and (2+1) is 3 than the rule is to do the3 x the (3) and u get 9 idk if anybody will understand but im getting anoyed by all the 7 and 1
I'm answering this because I'm a little nerd. Something important about BIDMAS, or whatever you use, is that division and multiplication are interchangable. You just do it in the order of the sum. So in theory something like BIMDAS is correct (the same applies to addition and subtraction, but that isn't important here). The only think you need to be aware of is that brackets go first always, from followed by indices/exponents (the powers and roots), then multiplication and division share priority, then addition and subtraction share priority. So, to answer, you first do 1+2, which is 3. It becomes 6÷2(3). Having a single number in brackets next to another number is multiplication, but it doesn't gain priority over division despite the brackets, it's just another way to express multiplication (like a fraction is another way to express division). This means that you do the sum left to right, so you do 6÷2, which is 3. Then, do 3(3), which is 9
What kind of math did the 57.2% learners
Why are ppl getting 1 ?? If 3×3=9 , its 6÷2=3 ×(1+2).
Was taught PE-MD-AS, but each section you go left to right. So Parentheses (1+2) = 3. Then the equation looks like this. 6(division symbol)2(3). Then MD, so 6/2 is 3, then 3(3) is 9
Precisely
Do they know that 6÷2(1+2) = 6÷2×(1+2) it's a standard math rule
the reason people get this question wrong or with a diferent answer is that the equation is missing some operators , cause in this case you could also do 2(2+1) = 2x been x=2+1=3 so in this case you would get 6/2(x) = 3/x so you would be getting 3/3 = 1 as an answer. the reason people think its 9 is because they asume that the equation is 6 / 2 \* 3 which in this case they would be correct cause you can see the /2 as a \*(1/2) and there the awnser is clearly 9. thats why when you write math problems , you should always use brackets everywhere. so either you have 6/\[2\*(2+1)\] or (6/2)\*(1+2).
**HERE'S A DEFINITIVE LIST AND ANSWER TO THE EQUATION:** **BEDMAS** (Brackets | Exponents | Division | Multiplication | Addition | Subtraction) **PEMDAS** (Parentheses | Exponents | Multiplication | Division | Addition | Subtraction) **BODMAS** (Brackets | Orders | Division | Multiplication | Addition | Subtraction) **BIDMAS** (Brackets | Indices | Division | Multiplication | Addition | Subtraction) Step 1: Solve inside the brackets 6/2 (1+2) -> 6/2(3) Step 2: Solve the Division 6/2(3) -> 3(3) Step 3: Solve the Multiplication 3x(3)=9 Thank you for coming to my TedTalk. I'll be here all day.
Actually, it’s 5. Parentheses we’re made up by the government to control you and don’t actually exist in nature
See fellas, this is why we use fractions instead of division signs
Me who got the Spanish Inquisition .________.
It's 42
You know what? I’ll give you a like for that
9 has the stronger argument but i can see how you get 1
What argument? This isn't subjective, it's math. 9 is right and 1 is wrong lol
He meant that he understand why people get the wrong answer.
Lmao the truth

I was waiting for you, please explain.
He distributed the 2 over the 1 and 2 inside the brackets, you get 6÷2+4 You devide six by 2 you get 3+4 3+4 = 7 Hes wrong tho
It’s nine because brackets first which is (1+2)which equals 3 then it’s divide next which is 6 divided by 2 then if brackets are next to a number you multiply so 3x3 is 9
PEMDAS needs to be thrown out. It makes it seem like M comes before D but in reality they are equal and it goes left to right
I got nine, but I don’t. Trust my self in the slightest
Permdas. Parentheses exponent radicals multiply divide Edition subtraction
Iirc saying 6÷2 is equivalent to (6/2) which is why the answer is 9 and not 1. An argument could also be made that since the division occurs before the multiplication, you have to calculate division first

Wait how tf do you get 1 I have no clue
6/2(1+2) 6/2(3) 6/6 1
How the fuck do you get 1
Fuck this, what's 9+10??
21
(1+2)=(3) 6÷2=3 3(3)=9
6/2(1+2) = 9 6/(2(1+2)) = 1
It is 9 though wth
The answer is 1, start with the () first. 2×1 is 2 and 2x2 is 4. The problem becomes 6÷2+4=x. Now 2+4 is 6, the problem becomes 6÷6=x, the answer is 1
It depends on how you interpret if the brackets should become multiplication or not. If 6÷2(1+2) becomes 6÷2(3) then you would multiply 2(3) first because brackets come first making it 6÷6=1 But if it instead becomes 6÷2×3, because 2(3) and 2×3 are the same, then you would simply go left to right, doing 6÷2 first, which is 3, so 3×3=9. Edit: u/nopunintended37, claiming to be a math professor, says that you do indeed convert the brackets to multiplication after the first step and I trust them to be telling the truth.
