Substitution

Substitution refers to the process of replacing a particular element within a system, formula, or context with another. In mathematics, it involves replacing a variable with a specific number or expression to solve equations or simplify problems. In general, substitution helps to make complex situations more manageable by swapping out parts for easier-to-work-with alternatives. It’s widely used across various fields like math, language, and programming to streamline processes, test options, or solve problems more efficiently. Essentially, substitution is a method of replacing one component with another to achieve a desired outcome or clearer understanding.
