Math 3 - Order of Operations

Use this strategy when determining the order of operations.

PEMDAS

1. Please-The “P” stands for Parentheses (brackets), Always do the operations in inner brackets First!!
2. Excuse- Exponents are next. Do all the square roots or powers.
3. My Dear- Multiply and or Divide from the left to the right.
4. Aunt Sally- Add and Subtract from the left to the right.

What we do is write out the problem in a notebook, then start from the beginning. “P” for parentheses.

For example:
5 x (9-4) +6 =
5 x 5 +6=

So far we have added the numbers in brackets, following order of operations, and our answer has been written underneath the sign of operation in brackets. Now we will Multiply my dear!
5 x 5 + 6=
25+ 6=

Finally Aunt Sally, we will add
25 + 6= 31
