retardedboss (12/02/2015) [-] Technically it is both 1 and 9
in order for there to be an exact answer it needs to be written more explicitly.
Some places it is taught to go left to right when two operations have the same priority others it's right to left. Use more parentheses or brackets and you will be able to make an equation that has only one solution.

rulebysecrecy (12/02/2015) [-] we learned it BEDMAS which puts division before multiplication in your case... you do it in the ORDER of when they appear when practicing ORDER of operations.

crilleballe (12/02/2015) [-]
The orders of operations puts multiplication and division on equal level.
Any division of a number by another number is the same as the multiplication of the first number by the reciprocal number. Similarly, a number minus another is the same as the first number plus the negative of the other number. And, the n-root of any number is equal to that number to the power of the reciprocal number.
x - y = x + (-y)
x / y = x * (1 / y)
n-root( x ) = x^(1/n)
Thus, division and multiplication is in some way the same thing, like addition and subtraction, and exponents and roots are the same thing. Thus, putting one before the other really is meaningless. Parentheses are before exponents and roots, that are before multiplications and divisions, that are before additions and subtractions.

deltoraquest (12/02/2015) [-] 6/2(1+2) = x
.: 6/2(3) = x
.: 3(3) = x
.: 9 = x
I found the answer is 9...
now some people may say "you have to solve the brackets and simplify that first" but here's the thing: shut uppa with the shut uppa, you solve everything IN the brackets then treat the result like a regular ass number, which in this case is being multiplyed, however the divide comes first in this equation

I’ll have you know I graduated top of my class in the Navy Seals, and I’ve been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I’m the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the **** out with precision the likes of which has never been seen before on this Earth, mark my ******* words. You think you can get away with saying that **** to me over the Internet? Think again, ****** . As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You’re ******* dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that’s just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little **** . If only you could have known what unholy retribution your little “clever” comment was about to bring down upon you, maybe you would have held your ******* tongue. But you couldn’t, you didn’t, and now you’re paying the price, you goddamn idiot. I will **** fury all over you and you will drown in it. You’re ******* dead, kiddo.

NO, goodhomer is right.
The divide sign is not used in higher arthimatic, specifically because it causes difficulty in determing the correct order of operations.
If the equation was written correctly it would have had the 6 as a "fraction" of the rest of the function, allowing you to determine the correct order of operations.
(Or the function as a denominator of the 6)

InfraBread (12/02/2015) [-] When you do:
6
--------- = x
2(1+2)
you're insinuating that the equation is written as 6%(2(1+2)) = x
The equation is 6 % 2(1+2), so therefore:
6
-- (1+2) = 3(3) = 9

you are correct
using pemdas the 1+2 goes first. then multiplythat by two which you will get 6/6
the answer is then factored down to 1

drpenguinz (12/03/2015) [-] im using a calculator everyday. its just not true. "/" is just multiplying with the inverse of the next argument, therefore the operators / and * have to behave the same way. thats how math do.

bigbadplaid (12/02/2015) [-] The problem with this is that it comes down to writing, and then also how it's computed.
On paper, it's 9, because once the bracket is solved, its a regular number, 3, which turns the equation into 6 / 2 X 3 (Following BEDMAS, we get 9).
HOWEVER, when a machine is tasked to solve this, you'll notice EVERYTHING beyond the division line is considered the denominator, which gives us 6 / 6.
It's purposely written like this to **** with you.

kanedam ONLINE (12/02/2015) [-]
it depends.
technically the equation is wrong because the sign for multiplication is missing between "2" and "(1+2)"
but thats not a big problem, because it is taught that it automatically means it gets multiplicated. the little thing to consider here is: the one who wrote the equation. if you write down something like "2*1(1+3)" usually means to first multiplicate the "1" and "(1+3)" and only afterwards do the other multiplication (in this case it wouldnt matter, but in the case of the posting there is a difference)

you always do brackets first.
now this is kinda bad layout but it still shows 2(1+2) as a single entity, if it was (6/2) *(1+2) it would be 9, if it showed 6/2*(1+2) it would be a toss up how you wanted to do it (cos that is awfull format). but because it is 6/2(1+2) it works out as 6/(2*(1+2)) giving you 6/6=1 because as i said at the start you always do brackets firstr
(1+2) in the bracket first, followed by whatever times the bracker which here is 2 then the multiplications/division outside the bracket which here is 6/everything else
resulting as i said in 6/(2*(1+2)) =6/6=1

thats a different case entirely, because there are no brackets in that case its not 6 -(3+3)
its 6+(-3)+3 they are 3 seperate entities as such they dont compound.
whereas 2(1+2) is one entity, as such in the 6/2(1+2) you treat 2(1+2) as (2+4) whereas if it was (6/2)(1+2) it would be 9 because in this case the 6/2 is treated befor the 2(1+2)
its 6+(-3)+3 they are 3 seperate entities as such they dont compound.

zaphodcoolfrood (12/02/2015) [-] All these god damn people fighting over this **** like it matters. There are two answers because the question is formatted to be contradicting and confusing. The argument to be made for 9 is PEMDAS and the argument for 1 is that it's 2(1+2) not 2*(1+3) which have the same result but which are not technically the same. There isn't one correct answer.

lapsushominum ONLINE (12/02/2015) [-] Because of the way the 2(1+2) is written my brain wants to group that to one term and then divide 6 by 6 to get 1, but that's wrong, which is really the purpose of the problem.

PEMDAS

we treat the 3 in the brackets as a multiplication value
do the equation left to right if all that remains is multiplication/division
