1. A standard way to simplify mathematical expressions and equations.
Order of Operations
A standard way to simplify mathematical expressions and equations.
Purpose:
Avoids Confusion
Gives Consistency
For example:
8 + 3 * 4 = 11 * 4 = 44
Or does it equal
8 + 3 * 4 = = 20

2. The Rules: Simplify within Grouping Symbols Simplify Exponents
( ), { }, [ ], | |
Simplify Exponents
Raise to Powers
Complete Multiplication and Division from Left to Right
Complete Addition and Subtraction from Left to Right

3. Back to Our Example For example: 8 + 3 * 4 = 11 * 4 = 44
8 + 3 * 4 = 11 * 4 = 44
Or does it equal
8 + 3 * 4 = = 20
Using order of operations, we do the
multiplication first. So what’s our
answer? 20

4. How can we remember it? Parenthesis - Please Exponents - Excuse
Multiplication - My
Division - Dear
Addition Aunt
Subtraction - Sally
