WebSometimes in math we describe an expression with a phrase. For example, the phrase. " 2 2 more than 5 5 ". can be written as the expression. 2 + 5 2+5. Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable).
