Inequalities - GCSE Maths Definition

Reviewed by: Dan Finlay

Last updated

In mathematics, 'inequalities' are statements that show the relationship between two values when they are not equal. Instead of using an equals sign, inequalities use signs like greater than (>) or less than (<). For example, if you have two numbers, like 3 and 5, you can write the inequality 3< 5, which means 3 is less than 5.

Inequalities can also include the symbols ≥ (greater than or equal to) and ≤ (less than or equal to). These are used when one number is either larger than or exactly the same as the other number.

Understanding inequalities helps you compare numbers, find ranges for variables, and solve problems in algebra.
