Описание: Inequalities serve as mathematical expressions that describe the relationship between two quantities, indicating that they are not equal. These mathematical statements are crucial for modeling and understanding various real-world situations where quantities may vary in magnitude. Inequalities are represented using symbols.

The concept of inequalities extends beyond numbers and applies to variables, expressions, and equations. In algebra, inequalities play a fundamental role in expressing the range of possible values for a variable, defining constraints, and establishing conditions for solutions to problems.

Inequalities are often encountered in diverse fields such as economics, physics, engineering, and social sciences. For example, they can represent constraints in optimization problems, describe the relationship between different variables in scientific experiments, or model economic disparities.

Understanding and solving inequalities involve manipulating mathematical expressions and applying logical reasoning. Graphical representations on a number line or in a coordinate plane provide visual aids that help convey the relationships between quantities and make it easier to interpret the solutions to inequalities.

In summary, inequalities are a powerful mathematical tool that allows us to express and analyze relationships between quantities that are not necessarily equal. They find applications in various disciplines and contribute significantly to problem-solving, decision-making, and modeling in a wide range of real-world scenarios.
