Description: An inequality is a relationship that holds between two expressions that are not equal, implying that one is greater or less than the other. In mathematics, inequalities are fundamental for expressing order relations and are used to solve problems involving inequalities. Unlike equations, which establish an equality between two expressions, inequalities allow for greater flexibility in describing possible ranges of values. Inequalities can be simple, such as x > 5, or complex, involving multiple variables and conditions. Additionally, they can be linear or nonlinear, depending on the nature of the expressions involved. In computer science, programming, and data analysis, inequalities are essential for decision-making, optimization, and modeling problems. In summary, inequalities are key mathematical tools that allow for the representation and analysis of situations where relationships of inequality are relevant.
