👉 Restriction math is a branch of mathematics that deals with constraints on mathematical expressions or functions, often aiming to find solutions within specific limits. These constraints can involve inequalities, such as bounds on variables or values, and are used to narrow down the set of possible solutions. For example, in optimization problems, restriction math helps identify feasible regions where variables must lie to satisfy given conditions, such as non-negativity or upper bounds. This approach is crucial in fields like economics, engineering, and computer science, where practical limitations must be considered to derive meaningful and applicable results.
