What is a mathematical phrase made up of numbers and variables connected by addition or subtraction operators?

A mathematical phrase made up of numbers and variables connected by addition or subtraction operators is called an algebraic expression. For example, the expression (3x + 5 - 2y) consists of the variables (x) and (y), along with the constants 3, 5, and -2, combined using addition and subtraction. Algebraic expressions do not include equality signs or inequalities.
