Abstract
This article examines how to solve equations with the module. The most difficult tasks of school mathematics are the equations containing variables under the module's sign. In order to successfully solve these equations, it is necessary to know the definition and basic properties of the module. When solving equations containing modules, the main concern is to remove the modules and thus obtain an algebraic equat ion. We can remove the module of an algebraic expression if we know the sign of expression, which is not always simple, sometimes requiring many calculations. Naturally, students should have the skills to solve such equations.
