I belong to the second group. In the first solution you can't just make the parentheses disappear, they should still be there. So the solution will be 2.

You can add/remove parenthesis wherever you want as long as what is inside has been resolved.

In this case that doesn't work though. There's another way to solve this and get the answer 2:

48/2(9+3) = 48/(2*9 + 3*2) = 48/(18+6) = 48/24 = 2

You can't do that!

You can only add/remove a parenthesis if what's inside has already been resolved remember. So you have to add 3 to 9 first.
