But havn't you done it as if...

(48/2)(9+3) ...... Presuming there are extra brackets?

I'm not saying you're wrong, just wondering.

For me it all comes down to whether you do the multiplication or division first.

I think the answers 2 for the reason that what's in the brackets should be multiplied out first. But I think it's 288 by going left to right once the addition is done.

Huh?
There's no questions about that, just like adding and substracting are equal and you go from left to right, multiplication and division are equal and you go from left to right

You do (9+3) first, and then go left to right.
