6÷2(1+2)
6÷2x3
3x3
9

it's 9, how stupid you should be to aswer 1. First 6/2=3 second 1+2=3, third 3*3=9. Easy.

The math in this thread is astounding.

outstanding**** (?)

And the answer is 9. end of story

[Bobzor]

I did it like this.
1+2=3
2x3=6
6/6=1
Answer is 1

Isn't this the correct way? No matter what your crappy calculator or w/e is telling you?

After further looking into it and actually thinking a bit the answer is 9 ;0

Let me help all of you that haven't passed third grade mathematics.

You do what's in the parentheses first, which leaves 6/2*3, and thus go from left to right. Which is 9.

[Nurvus]

As far as i know multiplication has priority, so you have to do the addition in the parenthesis while multiplying it by 2. So it's 6/6=1

You have 6÷2*(1+2)... not 6÷(2*(1+2))
So the addition has priority, not the multiplication.
You are left with 6÷2*3... not 6÷(2*3).
The answer is 9... not 1.

6/2(1+3)
6/2*3=9

[Heldamon]

6/2 = 3

You do it wrong

[Deleted]

Left to right D>M in this case..

[ztanz]

6÷2(1+2)=
6÷2+3=
3+3=6

hahaha, hilarious x)

[schwarzkopf]

6÷2(1+2)=?

6/2*3 = 9 because Excel says so.

My understanding is that it is () then */ then +- ... (three priorities) with left to right overriding any ambiguity.

[Snoosie]

6/2(1+2) =

(1+2) = 3

6/2 = 3

3 * 3 = 9

This is correct.

I hope everybody that was wrong was trolling ;D this is like 2nd grade math

[Waif]

6÷2(1+2) = 6÷(2*1+2*2) = 6÷(2+4) = 6÷6 = 1

what is this i don't even..?

how can you get anything else from that than 9?

[Sharissa]

It's 9!!! Division and multiplication are read left to right, one is not prioritized over the other.

[Frozendekay]

9.

6/2(1+2) = 3(3) = 9.

[Deleted]

why would anybody choose such a horrible notation?

what you learn in school ist that after the 3rd grade or so you stop using the division symbol and write divisions as fractures. then shit like this won't happen and mess peoples heads up.

[Nellah]

I'm not sure if in my sleep deprived state I voted for 1 or 9, but the answer is 1 due to mathematical priorities. I mean, I learned about this stuff in fifth grade.

6 / 2(1+2) = 6 / 2(3) = 6 / 6 = 1. Since anyone older than 10 writes division as fractions anyway.

EDIT: And this was on Facebook a week ago, and people were just as bad at their elementary mathematics.

[Deleted]

Depends the way you calculate it:
((6)/(2))*(1+2) or 6/(2(2+1))

Answer to the first = 9
Answer to second = 1
However, the first one is the correct way to solve it, if it is written as it is.

[Mozu]

its 1, you can write it like this:

6
-----
2(1+2)

if you wrote (6/2)(1+2) it would be different. math noobs.

I'm glad I could quote this before it was deleted in shame.
