In order to get rid of that parenthesis you have to multiply, after you multiply, you can get rid of parenthesis and you have a problem that can be worked from left to right.
48 ÷ 24
Do they still teach that rule about parenthesis? |
You are doing what's in the parenthesis first. Otherwise you'd be multiplying by 9 and then adding 3 afterwards. The parenthesis must come first. I showed this to my wonderful assistant, and we had fun with this, but we were too busy in our Resource Room working on and having our students take a two part Geometry proof test that took precedence. I love working with kids on Algebra, but Geometry is not fun for most of us.
