Inequalities containing one inequality symbol are called simple inequalities, while inequalities containing two inequality symbols are called compound inequalities. A compound inequality is really two simple inequalities in one.
3<x<5 means 3<x and x<5
When we solve a simple inequality, we isolate the variable on one side of the in- equality. When we solve a compound inequality, we isolate the variable in the middle part of the inequality. Also, when solving a compound inequality, we must perform the same operation to all three parts of the inequality:left, middle, and right

Absolute Value Inequality
With "<" and "≤" you get one interval centered on zero;
With ">" and "≥" you get two separate interval;
With "<" and "≤" you get one interval centered on zero;
