Question 482(9+3)=???

Clearly the answer is 288, but apparently there are some people who insist the answer is 2. This has turned into some long debates on some forums. What say you, CL?

Let's see if I remember the order of operations. Parentheses first, then since division and multiplication are equal rank, you would just go from left to right?? My vote goes to 288.

Following that it-was-dumb-then but still clever "PEMDAS" method we got taught in HS..

482(9+3)=?

Paranthesis:
482(12)=?

No exponents, so multiply

48(24)=?

Divide...

4824= 2

multiplication doesn't have preference over division though... that's why order of operations can be taught as PEDMAS as well. Once you get to 482x12, you work from left to right, getting 24x12 which = 288

Equations within parenthesis first. Then multiply/divide before add/subtract.

People either incorrectly assume that you have to multiply before you divide (even though they have equal preference), and end up with 24/12 = 2, or they think you have to distribute the 2 into the parenthesis like there's a variable involved when there isn't, and they get 48/(18+6) aka 48/24=2.
