It's 9. It can be 1, if you screw up the order of operators. There's an interesting video made by MindYourDecision that explains this in detail.

https://www.youtube.com/watch?v=URcUvFIUIhQ&t

Basically, the answer is 9, based on modern order of operation if you write:

6 ÷ 2(1+2)

https://www.symbolab.com/solver/step-by-step/6%20%5Cdiv%202%5Cleft(1%2B2%5Cright)


The answer is 1 if you write it like this:

6 ÷ (2(1+2)

https://www.symbolab.com/solver/step-by-step/6%20%5Cdiv%20%5Cleft(2%5Cleft(1%2B2%5Cright)%5Cright)

There you go.

Order of operations is something completely arbitrary, so nobody is really wrong, it's just that some people don't understand what the majority of us accept to be the proper order of operations.
PEMDAS is the usual one, but it is redundant, and many people don't remember that the M and D, or the A and S, can be swapped.
It should be PEMA, with the understanding that division is multiplication by reciprocal and subtraction is addition by negation. That would clear things up.

>÷
Into the trash it goes.

6/(2(2+1))=x
6/(2(3))=x
6/6=x
x=1

>>9057142
I agree, it should just be PEMA.

subtraction and division are illusory. division is sometimes denoted as ÷ because it is really just the multiplication of the reciprocal, which is why the division symbol itself looks like a fraction.

Also, subtraction is just the addition of a negative number which is why its the same exact sign as a negative sign. its just a shorthand notation that saves writing a plus followed by a negative for every negative addition operation

>>9056944
the answer is clearly:
(* (/ 6 2) (+ 1 2))
9

unless what is being divided is clearly defined it left/right

1

i remember a thread about this a while ago le engineers were saying 2(1+2) was its own term
why?

We have this same thread every day. God, just fuck off.

>>9057276
so instead of writing a sum as 1500000/500000, you'd write it as 1500*0.000002

>>9057320
duh you fuckin nigger

>>9057320

hes saying it should be

PEMA
DS

>>9057333

PEMA
___DS

The answer is 1. the only conceivable way you can get an answer other than one is if you do not prioritize the addition in the paranthese. This would be stupid since the very first step in the order of operations is the paranthese.

I did. He's wrong.

>>9057142
>order of operations is arbitrary
but it needs to be consistent for the sake of communication.
If a language meant to convey pure logic had multiple valid subjective interpretations then the language has failed. however the order of operations is set in stone, and thinking it "should be something else" is not valid

>>9057368
>it needs to be consistent
that is acknowledged in the same sentence you quoted
and sorry to break it to you, but no language is able to perfectly convey pure logic as long as two unique minds exist

>>9057368
Yes it needs to be consistent. That's what the parentheses are for! Otherwise you get an ambiguous mess like the pictured formula.

>>9057142
The symbols we use for digits and arithmetic operations are arbitrary as well. Does that mean it's impossible to answer a written arithmetic problem incorrectly?

>>9056944
6 * 1/(2(1+2) = 6 * 1/(2(3)) = 6 * 1/6 = 1

It's 9. Fucking engineering students.

When in doubt, parenthesize everything.
Or you could use the parentheses-free Polish/Reverse-Polish notations.
Order-of-operations isn't really math. It really is only a precedence hierarchy that people abide by so they can be lazy and omit the parentheses. I really think infix notation breaks people just like Roman numerals probably broke people's ability to do simple math thousands of years ago.

It's a horrible question, due to the ambiguous notation. Using [math]\div[/math] is just as retarded as writing [math]\times^{-1}[/math]

>>9056944
Independent of explicit instruction as to what order of operations conventions are being used, there is more than one answer. This is why conventions are discussed at the beginning of literally every math text. There's no such thing as a universal order of operations and if you think there is, you don't know 1/1000 of what you think you know about math.

just depends on where we are multiplying the 3

the problem is too vague obviously if you imagine it as 6/2(3) then it's 1, or 6(3)/2 then it's 9 and neither is wrong because only a retard would write it like that

>>9060346
>6/2(3) then it's 1

That's wrong though. You can even multiply by the inverse to prove it.
6 * .5 * (3) = 9. It's always 9. Some people are just brainlets about it. Heck the order doesn't even matter if you use the commutative property properly.

>>9060293
actually the division symbol is less ambiguous than using /

It's clearly division where / may be representing a fractional quantity.

6/2(1+2) = 6/(2+4) = 6/6 = 1

Why aren't mods deleting these threads?

Do we even have mods?

>>9062175
Did you think the equation was a fraction (despite the unambiguous use of the division symbol) or are you just using the distributive property incorrectly?

The correct answer is 9.

>>9056944
it boils down to 1/6*2*3
so 1

>>9056944
why the fuck you people keep asking the same trivial as fuck questions?
