All the ones who didn't rush in and pick the incorrect answer XD BODMAS Bracket Order Division Multiplication Addition Subtraction So you don't count the brackets as multiple by... brackets? :O | ||

It's however hard to imagine they still don't understand it after people explain it. This is why I f'in quit CS and went for a CIS degree, math is a pain in the ass! | ||

First: (9+3)=12 This gives you (48) / (2) * (12) Order of operations says multiplication and division are done in the same step, therefore if you have both remaining, you go in the order that they show up. So (48) / (2) is first. 24. (24) * (12) is 288. Disappointed to see so many twos. P.S. Yes I know in PEMDAS multiplication comes first, but PEMDAS should really be PE(MD)(AS), since multiplication and division, along with addition and subtraction, are done in the same step. Edit: Had multiple frowny faces due to parentheses =( | ||

48÷2(9+3) Brackets mean this comes first = 9+3 = 12 The number out side of brackets prioritises over division so; 2*12=24 48/24 = 2. Right? Or did i mis-memorise something. | ||

48 / (2*12) 48 / 24 2 instead of this: 48 / 2 * 12 24 * 12 288 Gotta remember, solve the brackets then re-evaluate! | ||
