#### Structure of Algebraic Expressions

Algebra is a branch of mathematics that uses symbols. A variable is a symbol, usually a letter, used to represent a number. An algebraic expression is a combination Of variable . numbers. and at least one For example, the expression n + 2 represents the phrase the sum of an unknown number and two. In this case. n is the variable

Any letter can be used as a variable, but the letter x is commonly used TO avoid confusion with x as a multiplication symtXl, multiplication is shown in other ways. Division can also written in different ways

Words

five times the variable x

five times x divided by 3

five times twice the value of x
