Re: 48÷2(9+3) = ??
Quote:
48/2(9+3)=? 48/2(12)=? 24(12)=288 2(9+3) reads as 2*(9+3). As PEMDAS states, Multiplication before Division or vice versa from left to right. If it was 48/(2(9+3)), it would force the multiplication so you would get 48/24=2. That's using PEMDAS of course. Don't know how other people are taught. =/ Yeah, close thread. This isn't a math forum. Last edited by ninjalostboy95; 04-10-2011 at 01:25 PM. Reason: I read some weird "÷" symbol. |

) we always multiply by whatever the answer in the parenthesis is before any other multiplication or division is done. With that said in all other instances you normally multiply or divide starting from left to right, so I could see how some people could get 288. That just isn't how I've always seen it done,
