48÷2(9+3) = ???

Oh damn. This made some sense.

So its 2?

You finish the RIGHT set right to obtain 24. then you divide to get your 2.

Others seem to think once you get the 12, you jump from the right back to the far left and follow the M/D rule. But you have to totally complete the parenthesis first, correct? To get 288, everyone is just forgetting about the parthensis and totally treating it as a standard multiplication.. Nice catch.. You have to finish the right side then you can jump to the left.. I knew It didnt make sense to just leave the 12 and jump to the left. Then you got these guys just changing the problem to where ( equals *.

Debate for days ensues Im sure

Distributive property of multiplication over addition. Early Algebra problem.

The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (2*9+2*3). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it. You do NOT compute this expression from left to right until you use Algebra to simplify the statement 2(9+3).

So this can be rewritten as:
48 / (2*9 + 2*3)

Which leaves us with

48 / 24 = 2

Answer = 2.

Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 * (9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (2*9+2*3). Be very careful with your signs.

at this debate. The answer is 288. you don't always multiply before you divide (which is what a lot of people are doing). the division sign is before the multiplication sign.

Whatttttt????

Dude, PEMDAS...Parenthesis first, so the first thing you gotta tackle is the (9+3), which gives you 12.

Your equation then becomes 48 / 2(12).

According to the PEMDAS rule, multiplication has precedence over division so the next order of operation is 2x12, which gives you 24.

And finally, 48/24 = results in 2.

This isn't rocket science people...

Edit: Multiplication and Division DO NOT have the same priority.

peMDas...M comes before D; it aint peM/Das...

You all KEEP FORGETTING! PEDMAS OR PEMDAS OR PEDMSA OR PEMDSA they are all the same.

The multiplication and division are interchangeable, so you go left to right in the equation, the Addition and Subtraction are interchangeable as well.

You getting to =2 this way are getting there for the wrong reasons.
