What proof means

Flowchart of algebraic proof forms showing integer n, even 2n, odd 2n+1, consecutive numbers, and target forms like 2k+1, mk, and p^2

A proof is a logical argument that shows a statement is true for every allowed value. Testing a few numbers can suggest a pattern, but it cannot guarantee the pattern always continues.

Maths
Proof

Step-by-step lessons covering CIE IGCSE Maths Proof for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 3 (Core) or Paper 2 and Paper 4 (Extended) format. Start with the Core-tier fundamentals in number and algebra before moving on to the more demanding Extended-only topics like calculus-adjacent algebra and advanced trigonometry.
