Absolute Value:
Absolute value measures the distance from the origin to any number on the number line.

This tutorial shows the properties of absolute value equations and how are they used in problems. Absolute values are presented with the use of graphical examples. Linear equations and absolute values are used concurrently in problem solving examples.

Absolute value inequalities are solved in this tutorial with the use of the principles concepts of linear inequalities and common strategies to solve algebraic equations. It is important to know in this Algebra 2 course that absolute values are probably the most common principles used in higher mathematics courses.
