*(Concise Encyclopedia)*

In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. Commonly used variables include *x* and *y* (real-number unknowns), *z* (complex-number unknowns), *t* (time), *r* (radius), and *s* (arc length). Variables should be distinguished from coefficients, fixed values that multiply powers of variables in polynomials and algebraic equations. In the quadratic equation *a**x*^{2} + *b**x* + *c* = 0, *x* is the variable, and *a*, *b*, and *c* are coefficients whose values must be specified to solve the equation. In translating word problems into algebraic equations, quantities to be determined can be represented by variables.
