Order of Operations

A mathematical operation that is. DS (4th grade) did his semester assessment today in most of his lessons. We learned about the order of operation early in the school year, both of us had to review on what we covered from the beginning. So, I am putting it here for an easy access for me.
  1. Start with the numbers inside the parenthesis ()
  2. Then multiply or divide, what ever comes first from left to right
  3. Then add or subtract, what ever comes first from left to right
I know this is very easy, however, it's hard to do the operation when you forget which one to do first.
