How to Work With Absolute Value Inequalities, Step by Step

absolute value inequalities: absolute value sample

You might already be familiar with solving inequalities, but what happens when you add an absolute value expression into the mix? Let’s go through the steps it takes to solve absolute value inequalities.

The absolute value symbol looks like this: |a|, where a is any real number. The absolute value sign means that the expression is no longer just a, but the distance a is from 0 on a number line.

A quick example: |2| = 2, because positive 2 is a distance of 2 from 0 on a number line.

Similarly, |-2| = 2, because negative 2 is also a distance of 2 from 0 on a number line.
