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

This tutorial shows the absolute value equations and their properties. The geometric definition of an absolute value is shown with the use of graphical examples. There are examples that show how absolute linear equations are solved. The importance of absolute value equations is mentioned in this tutorial.

The principles of solving absolute value inequalities are seen in this tutorial. The ways how solving absolute linear inequalities are shown in the examples provided. A review of the basic principles of inequalities is introduced to show the techniques to solve a linear inequality.
