Intro

Equivalent Expressions

By the end of this lesson, you will rewrite an expression as an equivalent expression using properties of operations. Two expressions are equivalent when they always have the same value, no matter what number you use for the variable. We will use properties like commutative, associative, identity, inverse, and distributive to do this.
