  1. Order of Operations

 Order of Operations:
When you solve math problems, you need to follow the order of operation:
Parentheses, Exponents, Multiplication/Division, Addition/Subtraction (PEMDAS)
There is a phrase that helps people remember this: Please Excuse My Dear Aunt Sally
40 – 2 x 4²                                   5 x 3 + (7 – 1)
Step 1: Exponents 4² = 16                   Step 1: Parentheses 7 – 1 = 6
New Problem: 40 – 2 x 16                    New Problem: 5 x 3 + 6
Step 2: Multiplication 2 x 16 = 32          Step 2: Multiplication 5 x 3 = 15
New Problem: 40 – 32                        New Problem: 15 + 6
Step 3: Subtraction 40 – 32 = 8             Step 3: Addition 15 + 6 = 21
