What is an algebraic expression?

In GCSE maths, an algebraic expression is a combination of numbers, variables and mathematical operations, such as addition, subtraction, multiplication, division and powers. An algebraic expression can consist of a single term (such as 2 x) or multiple terms (such as 2 x plus y minus 3 z). Here are some examples of algebraic expressions:

  • 2 x

  • x squared plus y squared

  • square root of x plus 1 end root

  • 2 over x

Algebraic expressions can be simplified by collecting like terms. For example, 2 x plus 3 x plus x can be simplified to 6x. Expressions do not contain an equals sign. For example, 2 x plus 1 equals 5 x minus 2 is an equation, not an expression. However, each side of the equation contains an algebraic expression, 2 x plus 1 on the left and 5 x minus 2 on the right.
