Olympic College Topic 1 Algebraic ExpressionsPage | 1 Algebraic Expressions 1. Introduction:Definition: In algebra, we use letters such as x, y and z to represent unknown numbers. For example 5x + 4y an algebraic expression. In this expression we call x the variable and 5 is called the coefficient of x. We can treat mathematical expressions in the same way as numbers provided we obey certain rules of algebra. We can also translate information that is given in English into an equivalent mathematical form using algebraic expressions? 8 x
