By the end of this tutorial students will be able to solve absolute value inequalities with one variable

Students will be able to graph absolute value inequalities on a number line using the two solution inequalities

This tutorial introduces students to solving absolute value inequalities following four simple steps:

1) Balance so the absolute value is alone

2) Write two inequalities (a positive absolute value and negative absolute value equation)

3) Balance the inequalities

4) Check your solution by substitution and/or number line

The tutorial uses a handful of examples to demonstrate the steps.

**ABSOLUTE VALUE:** The distance between a number and zero on a number line

**INEQUALITY: **A symbol that denotes a mathematical relationship where two expressions are not equal (<, >, __<__, or __>__)
