The process of determining the variables in mathematical equations or expressions is about spotting those quantities that are unknown. This necessitates a clear comprehension of the context, separating the variable through algebraic computations, and then resolving the equation. This procedure is essential in multiple mathematical fields like algebra, calculus, and statistics.
