What is the definition of an inequality?

An inequality is defined as a mathematical sentence that includes symbols such as less than (<), greater than (>), less than or equal to (≤), and greater than or equal to (≥). These symbols are used to express a relationship between two values or expressions that are not necessarily equal. For example, the inequality x > 5 indicates that x is greater than 5, establishing a relationship in which there are multiple possible values for x rather than a single value that satisfies an equation.

While the concept of describing relationships between numbers is significant, it is essential to specifically note that inequalities utilize particular symbols to convey those relationships. Hence, the answer focused on the inclusion of these specific inequality symbols is the most accurate definition.
