Algebraic Expression - Definition and Examples

An algebraic expression is a mathematical phrase that can include numbers, operations symbols, and most importantly variables. 

Because variables are important elements, algebraic expressions are sometimes called variables expressions.

An algebraic expression does not have an equal (=) sign

For example, x + 8 - y = 12 is not an algebraic expression.
