What Is an Inequality Calculator?
An inequality calculator is a specialized tool designed to solve mathematical inequalities. It can handle a wide range of problems, from simple linear inequalities to complex polynomial, rational, and absolute value inequalities. These calculators are invaluable for students and professionals as they not only provide the final solution set (often in interval notation) but also offer detailed, step-by-step explanations that illuminate the process of isolating the variable and determining the correct solution.
