### Order of Operations

A standard way to simplify mathematical expressions and equations.

• Avoids Confusion

• Gives Consistency

For example:

8 + 3 * 4 = 11 * 4 = 44

Or does it equal

8 + 3 * 4 = 8 + 12 = 20

that mathematicians have agreed to

when simplifying mathematical expressions

or equations. Without these simple, but

important rules, learning mathematics would

• 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

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
