Definition

A variable does not have a set value. Its value can change, and a variable is used to represent unknowns in equations.

Any symbol may be used as a variable, but the most common variables are x, y, z, n, i, a, b, and c.

Examples

What plus 7 is 10?

Write an equation that uses a variable to represent the part that is unknown.

$\displaystyle7+n=10$
