43 Order of Operations  ( ) + - X

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

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

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

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

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

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

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

Let’s Try Some  Problems!
