Olympic College Topic 1Algebraic ExpressionsPage | 1Algebraic Expressions1. 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 5is called the coefficient of x. We can treat mathematical expressions in the same way asnumbers provided we obey certain rules of algebra. We can also translate information that isgiven in English into an equivalent mathematical form using algebraic expressions?If a statement is given in English that uses the four basic arithmetic operations of addition,subtraction, multiplication and division we can translate this information into an equivalentalgebraic expression.For example.p multiplied by 3 can be written as the expression 3p11 added to x can be written as the expression 11 + x8 subtracted from r can be written as the expression r8m multiplied by 4 can be written as the expression 4m4 multiplied by m can be written as the expression 4mx divided by 4 can be written as the expression4 divided by x can be written as the expressionWhen you combine more than one variable you can also express the information as algebraicexpressionsFor example.x added to y can be written as the expression x + yx subtracted from y can be written as the expression yxa multiplied by b can be written as the expression ab4 multiplied by m squared can be written as the expression 4m2x divided by y can be written as
