Solving Compound InequalitiesVideos, worksheets, games and acivities to help Algebra 1 students learn how to solve coumpound inequalities.
Compound Inequalities In mathematics, it can be useful to limit the solution or even have multiple solutions for an inequality. For this we use compound inequalities which are inequalities with multiple inequality signs. When solving compound inequalities, we use some of the same methods used in solving multi-step inequalities.

Compound Inequalities
Compound Inequality Students learn that when solving a combined inequality "or" means "union", or everything that's mentioned in the two inequalities. And when solving a combined inequality "and" means "intersection", or only what's in common to the two inequalities. So when graphing a combined inequality, the first step is to graph the inequalities above the number line, then combine them on the number line based on "or" (bring everything down to the number line) or "and" (only bring down the parts where the graphs overlap).
