I learned that bruins won

was actually curious about this because I wasnt sure if parenthesis includes distributing parenthesis or just finding what's inside the parenthesis

quick google search and I found:

Depending on how you approach the problem either distributing or doing the parenthesis first, you will get two answers, 9 and 1. You can also right off treat it as 6/2(1+2) and since the 2 is a factor, you can cancel the 6 and 2 and are left with 3/(2+1)=1

without a proof you can not say either is correct so to prove this, we will let the 1, in (1+2) equal x, and set the problem equal to both 1 and 9.

Okay, Mathematician reporting in.

Everyone answering 1 is a fag and should go back to first grade.

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

Divisions aren't done after multiplications; they're done at the same time, in a left to right order.

So many idiots in all these math threads people make. Jesus..

Quoting the truth because it is.

@Mastersam : You don't distribute before solving the parenthesis; and you do the operations from left to right regarding multiplications/divisions.

that's exactly what I thought

but his proof seems to make sense

now i'm just trying to think if it's actually illogical to sub in x for 1 in some way

like, when x = 2, X^2 = 4, but that doesnt mean y always equals 2x, like in his proof it just happened to also equal 1.

ahahaha

Seriously...

these results are embarrassing.
