A compound inequality (or combined inequality ) is two or more inequalities joined together with or or and . To be a solution of an or inequality, a value has to make only one part of the inequality true. To be a solution of an and inequality, it must make both parts true. (In other words, x≥−1 and x<2 .)

Compound inequalities are inequalities that have been joined by the words “and” or “or.” For example: − 2 < x ≤ 5 Read, “ is greater than -2 and less than or equal to 5.” x ≥ 3 or Read, “ is greater than or equal to 3 or less than -4.” Notice that both of these inequalities have two inequality signs.
