An inequality is a mathematical statement that two expressions relate in one of several conventional ways:
- $a < b$
- $a \le b$
- $a > b$
- $a \ge b$
A statement of the form:
- $a \ne b$
may or may not be considered an inequality.
Let $\RR$ be an inequality.
Let $a \mathrel \RR b$.
Then both $a$ and $b$ are referred to as members of the inequality $\RR$.
