I'm seriously wondering where ya'll went to school because this is sad. I was a beast in math so this is nothing compared to Upper level courses i took later on, this is extremely basic
288 again
* In Mathematics, the order in which mathematical problems are solved is extremely important.
Rules
1. Calculations must be done from left to right.
2. Calculations in brackets (parenthesis) are done first. When you have more than one set of brackets, do the inner brackets first.
3. Exponents (or radicals) must be done next.
4. Multiply and divide in the order the operations occur.
5. Add and subtract in the order the operations occur.
Read above.

I still say the answer is 2. both have compelling arguments, but I'm going with mine. 14 motherfucking pages.
The answer is 2.
Look up P.E.M.D.A.S. idiot.
YOu kidding me right, "look up pemdas"?
again 2(anything) is treated as 2*(anything), period
OMG
Distributive property will only be a factor if the numbers outside with division or multiplication are resolved already
and "idiot" too?
damn

you right
Good Job homey!
I bet you there are no (accredited)examples anywhere which point to the solution being 2
should be able to dead it here. I know it ain't though
The answer is 2.
Look up P.E.M.D.A.S. idiot.
Did you look it up
A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. If you're not sure of this, test it in your calculator, which has been programmed with the Order of Operations hierarchy. For instance, typesetting this into a graphing calculator, you will get:
calculator screen-shot: 15 / 3 * 4 = 20
Using the above hierarchy, we see that, in the "4 + 2×3" question at the beginning of this article, Choice 2 was the correct answer, because we have to do the multiplication before the addition.
(Note: Speakers of British English often instead use "BODMAS", which stands for "Brackets, Orders, Division and Multiplication, and Addition and Subtraction". Since "brackets" are the same as parentheses and "orders" are the same as exponents, the two acronyms mean the same thing.)

Mnemonics are often used to help students remember the rules, but the rules taught by the use of acronyms can be misleading. In Canada the acronym BEDMAS is common. It stands for Brackets, Exponents, Division, Multiplication, Addition, Subtraction. In other English speaking countries, Brackets may be called Parentheses, or symbols of inclusion and Exponentiation may be called either Indices, Powers or Orders, and since multiplication and division are of equal precedence, M and D are often interchanged, leading to such acronyms as BIMDAS, BODMAS, BOMDAS, BERDMAS, PERDMAS, PEMDAS, and BPODMAS.
These mnemonics may be misleading, especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order "addition first, subtraction afterward" would also give the wrong answer.
10 - 3 + 2 ,
The correct answer is 9, which is best understood by thinking of the problem as the sum of positive ten, negative three, and positive two.
http://en.wikipedia.org/wiki/Order_of_operations
Position within the expression is used to determine the order of evaluation when two or more operators share the same operator precedence. Consider the following:
A = 6 / 2 * 3
In this case, A equals 9, since the division operator is to the left of the multiplication operator. The subexpression 6 / 2 is evaluated before the multiplication is done, even though the multiplication and division operators have the same precedence. Again, parentheses can be used to override the default evaluation order:
A = 6 / (2 * 3)
In this case, A equals 1, because the expression inside parentheses is evaluated first.
A useful rule of thumb is, "when in doubt, parenthesize". Some examples of expressions are provided in the following table.

Dont divide last when division comes first

No, division comes before multiplication if it's first from left to right.

look at example 3
once you do what's inside the (), the () disappear.

Yea. But if a number is before the Parenthesis, you have to solve it to move on. A number isnt before the Parenthesis in that example.
correct
16 pages and counting. Lurkers coming out of the base boards like roaches at 3:00AM.
Its gonna be a long night
And the answer is still 2
Prove that its 2.
family, this is the problem. Too many of you simply memorized this acronym without understanding it.
You do multiplication AND division in order from left to right.
12 ÷ 2 * 3 = 18, not 2
Re: DDisntRe: 48÷2(9+3) = ????
Ur really stupid if you think I said the answer was 288.
Ur really stupid if you think I said the answer was 288.
I think you read my answer too fast.
I'm saying that once you solve what's INSIDE THE PARENTHESES you proceed from left to right which means that once you get 12 from the (9+3) you work the problem from left to right.
48 divided by 2, which equals 24 then multply that number by 12 which gives you 288.
