An inequality is a mathematical expression that establishes a relationship of inequality between two terms or expressions. It is used to describe ranges or sets of values that satisfy certain conditions.
It can include symbols such as < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to).
Solving an inequality involves finding the values of the variable that satisfy the inequality. These are fundamental in mathematical modeling and are applied in situations where constraints or solution intervals are sought.
