Order of Operations

• A standard way to simplify mathematical
  expressions and equations.

3
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.

5
The Rules

• 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 whats our answer?
20
7
How can we remember it?

• Parenthesis - Please
• Exponents - Excuse
• Multiplication - My
• Division - Dear
• Addition - Aunt
• Subtraction - Sally

Summary

• Key points to remember that will give audience
