Module 1 - Lesson 4

In this module you will review absolute value and evaluating expressions

Lesson 4: Absolute Values and Evaluating Expressions

Expressions involve variables and numbers, but are not set equal to anything. When asked to evaluate an expression, we simply simplify! For Example: Evaluate x + 3, when x = 2 2 + 3 5

An absolute value is the distance from zero. Distance is always positive, so the absolute value of a number will always be positive. For Example: |-3| = 3
