  A mathematical expression that consists of variables, numbers and algebraic operations is called an algebraic expression. Each algebraic expression can contain several terms. For example, the expression above contains two terms: 30x and 20y. The numerical factor of each term is called a coefficient. The coefficients of the terms above are 30 and 20, respectively. When considering a variable term, we see that it is composed of a numerical coefficient and a variable part.
