GCSE Maths: Inequalities
Solve and represent inequalities on a number line. Practise it with adaptive questions for AQA, Edexcel, OCR and Eduqas.
What you need to know
The concepts examiners test on inequalities, and what each one is really asking.
Where marks get lost
The exam technique that separates a correct method from a correct answer.
- Flipping the sign when multiplying by a positive (only flip for negatives)
- Confusing open and filled circles on number lines
- Not flipping the sign when dividing by a negative
- Writing the inequality the wrong way round
Inequalities questions students ask
Is Inequalities on the Foundation paper?
Yes. Inequalities appears at both Foundation and Higher tier, though Higher papers take it further.
What should I know before starting Inequalities?
It builds on Solving linear equations and Negative numbers and Number lines. If those feel shaky, practise them first — Inequalities questions assume them.
What is the most common mistake in Inequalities?
Flipping the sign when multiplying by a positive (only flip for negatives).
Which exam boards cover Inequalities?
All four we support — AQA, Edexcel, OCR and Eduqas. GCSE Maths subject content is set by the DfE, so the topic is common to every board; what changes is the paper structure and the grade boundaries.
