48 / 2 (9 + 3) can also be expressed as 48 / (9+3) + (9+3)
48 / 12 + 12
4 + 12
= 16
Team 16 anyone?
48 / 12 + 12
4 + 12
= 16

Can we all agree that it is 288 now? There has been sufficient evidence to prove this time for Method Man to drop this 2 page response on why it is 288.

Those who say 2 need to go back to their elementary school teacher and have it taught to them again, because that's what this problem is, 6th grade math.
i think the answer is 288, my uncle, head of his math department, who has wrote 3 math textbooks and has his own math, says the answer is 2. i told him im not convinced. he laughed and said theres no convincing this is math and 2 is the answer. so before u call people stupid like i felt like doing until I checked, make sure ur right.

288.
Obviously you do the (3+9) first because it's in the parenthesis, giving you:
48÷2(12) which can be rewritten as 48÷2*12
Since ÷ and * are the same in order of operations, you go from left to right so 48÷2*12 = 24*12 = 288.

Question
Why does the left to right rule mean that you don't always do multiplication before division or addition before subtraction?
Answer
Hello, Raven.
This is the phrase to remember: Please Excuse My Dear Aunt Sally.
P is for Parentheses, E is for Exponents, M is Multiplication, D is for Division, A is for Addition, and S is for Subtraction.
Parentheses and exponents always come before the last four. However, multiplication and division are actually grouped together, as are addition and subtraction.
In actuality, it reads "Parentheses Exponents (Multiplication and Division) (Addition and Subtraction)."
Division is done before multiplication, or subtraction before addition, if they are further left in the problem.
For example, in the problem 5/5x6, the answer is 6. First, you have to divide 5 by 5, getting an answer of 1, and then multiply 6 by 1, giving you 6.
Hope this helps.
Regards,
John
