So i just spoke with my math professor and she says 288

48÷2(9+3)=
parenthesis first
48÷2(12)=
since Division and multiplication are the next step solve left to right
24(12)=288

this is always how i was taught i say 288 as well

Guess it's obvious that I haven't taken a math class since I was 15.:eek: I need a refresher course! And I took all the honors math classes.:eek:

that is incorrect because people forget that the 2 is connected to the parenthesis and therefore the problem should actually look like

__48__
2(9+3)

__48__
2(12)

__48__
24

the answer is therefore 2... the way the problem is written makes it easy to assume that going left to right is the most logical way to solve it...

You should have spent less time typing, and instead maybe 20 seconds on Google. It's your friend, you know! :main_laugh:

Oh, and ... Google Calculator

Google is not flawless as you can see by all the results you get when searching that have no correlation to the topic...

I dunno why I actually engage in this argument when it's known to be a troll... must be my math nerdy-ness showing through...:main_rolleyes::main_rolleyes::main_rolleyes:

so it's a troll because you disagree with the answer?
