In mathematics, an inequality is a relation that expresses the difference between two expressions, indicating whether one is greater than, less than, or equal to the other. Checking inequalities involves verifying whether the given relation holds true for a specific set of values or determining the range of values for which the inequality is satisfied.
Checking inequalities is essential in various fields, such as economics, physics, and engineering, where it helps analyze and solve real-world problems. It enables us to compare quantities, model relationships, and make informed decisions based on the results.
