An unknown in an algebraic expression is a variable that represents a value we do not yet know. It is typically denoted by letters such as (x), (y), or (z). The purpose of the unknown is to allow for the formulation of equations and the exploration of relationships between quantities. Solving the expression involves finding the value of the unknown that satisfies the equation.
