Order of Operations 
( ) + - X

2. The Order of Operations tells us how to do a math problem with more than one operation, in the correct order.

3. Please Excuse My Dear Aunt Sally
This will help to you to remember the order of operations. Just Change the P for G and you get GEMDAS

4. GEMDAS G
Groups :( parenthesis ) , [ brackets ] , √square roots, etc. E
Exponents 43 M D
Multiply x
Divide  A S
Add +
Subtract -

5. GEMDAS
Grouping ( ) [ ] √
Always do parentheses, brackets , square roots , any type of grouping 1st.

6. Please Excuse My Dear Aunt Sally
Exponents 43
Always do Exponents 2nd.

7. Please Excuse My Dear Aunt Sally
Multiply x
Divide 
Do multiplication and division 3rd, from left to right whatever comes first.

8. Please Excuse My Dear Aunt Sally
Add +
Subtract -
Do addition and subtraction 4th, from left to right whatever comes first.
