When simplifying an expression that has more than one operation symbol, there is a special order you must follow.

Parentheses

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

Be careful in steps 3 and 4! Multiplication does not always come before division, nor does addition always come before subtraction! For example, in you would multiply before dividing because it is to the left of the division. Similarly, you would subtract before adding because it is to the left of the addition.
