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 8 12 20

Order of operations are a set of rules that mathematicians have agreed to follow to avoid mass CONFUSION when simplifying mathematical expressions or equations Without these simple but important rules learning mathematics would be maddening

The Rules
1 1 1 2

Simplify within Grouping Symbols


Simplify Exponents
Raise to Powers

Complete Multiplication and Division from Left to Right Complete Addition and Subtraction from Left to Right

Back to Our Example
For example 8 3 4 11 4 44 Or does it equal 8 3 4 8 12 20 Using order of operations we do the multiplication first So what s our answer 20

How can we remember it
Parenthesis Exponents Multiplication Division Addition Subtraction
