1
Order of Operations A standard way to simplify mathematical expressions and equations.

2
Purpose Avoids Confusion Gives Consistency For example: 8 + 3 * 4 = 11 * 4 = 44 Or does it equal 8 + 3 * 4 = 8 + 12 = 20

3
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.

4
The Rules 1. Simplify within Grouping Symbols ( ), { }, [ ], | | 2. Simplify Exponents Raise to Powers 3. Complete Multiplication and Division from Left to Right 4. Complete Addition and Subtraction from Left to Right

5
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 whats our answer? 20

6
How can we remember it? Parenthesis-Please Exponents-Excuse Multiplication-My Division-Dear Addition-Aunt Subtraction-Sally

7
Summary Key points to remember that will give audience confidence or improve morale
