This is a tutorial on how to solve 48 ÷ 2 ( 9 + 3 ). The problem has been spaced out for your benefit. I'm doing this because I can (and because of this.) THERE ARE TWO WAYS OF SOLVING THIS PROBLEM SINCE THIS IS A TROLL PROBLEM. Why? PEMDAS and BEDMAS screw everything up...

PEMDAS:

Now, since everyone on Newgrounds should be at least ten years old, everyone should know the order of operations: PEMDAS. First, you do parenthesis, then exponents, then multiplication AND division, then addition AND subtraction. So, the first thing to the problem that you should do is solve the parenthesis in this problem.

9 + 3 = 12. So now we are left with:

48 ÷ 2 (12). When you have a parenthesis next to a number, it means you should multiply, so the problem is really:

48 ÷ 2 × 12.

Division and multiplication are of equal rank, meaning the equation needs to be solved from left to right. 48 ÷ 2 = 24. So:

24 × 12. Solve.

288. Don't believe me? Here's some proof, and there is some proof at the bottom of the page.

BEDMAS:

Everything about the addition in this problem can stay the same. However, things get different once the multiplication and division is reached. Because brackets come before multiplication, here is what happens.

Once you reach 48 ÷ 2 (12) (after adding what are in the brackets), because multiplying through brackets comes first, it is really:

48 ÷ 24.

2. (Note: This answer is also reached by using the distributive property.)

So really, there are two answers, depending on which system you want to use. Most answers for me come up as 288 because I live in America in a certain state you can easily tell I live in, which uses PEMDAS. However, using the other system, BEMDAS, a different answer will be reached.

I think I've been successfully trolled by completing this.

Texas Instruments?

Oh boy!

Oops. It seems I've leaked some information about myself.

I disagree. 48 ÷ 2 (12) has brackets in that I would expand first, leaving 48÷42=2

I fixed the news post to explain both solutions. This problem is worth asking a math teacher about. Also, you meant 48 ÷ 24 = 2. ;-]

Mathematics make my balls so wet.

I'm sure there's some sort of math that explains why that happens.
