wow, i still cant believe you two are still trying to convince everyone the answer is 288
and that you still remember what you learned 30 years ago vs what i learned 6 years ago in highschool and 3 years ago in collage lol
22 people on this forum did it wrong except mouse and dan got it right and 2 more, are you serious? i'm glad you two arent doing my taxes :P
you divide the 48 by the 2 i understand, but why the hell would you multiply it by 12 again! you're supposed to divide by it
48/2(9+3)=24/(12)=2
or
48/2(9+3)=48/(18+6)=48/24=2
you forgot where the teach said you can cross out the top and buttom as long as you can divide by the same number?
i will post this again
this paper explains it all, i really dunno what more to say lol

Also I sent this problem to my HS and my College math teachers. When I sent it to them as written in the OP they say I did it right. Also Sam, you can't argue with how I proved I was right, just remove the division.
48 * .5(9+3)
Since division is just the inverse of multiplication, get rid of it. Make it all multiplication. X = 288.
48 * .5(9+3)

My calculator must be programed wrong. All 3 of them.
First perform any calculations inside parentheses.
(9+3)=12
Next perform all multiplications and divisions, working from left to right.
48/2=24
24*12=288
Order of operations and inverse operations are two different things that'* why dividing 24 by 12 doesn't work, you have to multiply
