Any mathematical phrase that contains numbers, variables with algebraic operators (like +, -, *, / ) is called algebraic expression equation. The values of variables such as x, y or a, b can be changed accordingly. In this phrase, 3 and 7 are constant numbers while x represents a variable. Some other examples of an algebraic expression are the following;
