KS3 maths: Expanding and factorising: 20 questions, marked instantly with every answer explained. Free, no sign-up, no adverts in the test. This test is for Years 7 to 9 (ages 11–14). In the US, that's Grade 6 to Grade 8.
Before you start
20 questions on expanding brackets, factorising and simplifying expressions, picked at random from a bank of 45, so every try is different. Choose an answer. Some questions ask you to type an expression or an equation, such as 3(x + 2) or y = 2x − 1: any correct way of writing it counts, unless the question asks for a form (for example "factorise"). Choose Practice to see each answer explained as you go, or Test to see your score and explanations at the end.
- 20 questions – a new mix each time you try
- Type algebra with the keyboard or the on-screen maths keys
No sign-up and no adverts. Your answers stay on this device. Nothing you type in the test is sent to us – unless you choose to report a problem with a question.
How it is marked: by Classfern's own checks, in your browser, straight away. Typed algebra is marked by what it means, not by how it is spelled out, so equivalent answers count. Spot a mistake? Use the Report button.
