Absolute value inequalities require a slightly different approach. Solve the absolute value inequality Solving and graphing absolute value inequalities with two variables is also a skill that math teachers require students to master in algebra i.

The absolute value of any number is always zero or a positive value.

An absolute value inequality is slightly different to an absolute value equation, examples of which can be seen on the absolute value equations page. The absolute value of a number is the distance of a value from the origin, regardless of the direction. Sal introduces the concept of inequalities that contain absolute value expressions, and solves a bunch of examples. For example, the inequality 31 ≥ the number of days in a month is a true.

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can not be negative.
