What is a algebraic expression?

mathematical expression that consists of variables, numbers and operations.

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 7r² − 2rx + u is an algebraic expression. Since taking the square root is the same as raising to the power, is also an algebraic expression.
