What proof means

Flowchart of algebraic proof with boxes labelled define n, write even odd and consecutive forms, substitute and simplify, factorise into target forms, and conclude

In proof, checking a few examples is not enough. We use a letter such as $n$ to stand for any allowed integer, so the argument works for every case.

Proof

Step-by-step lessons covering Edexcel GCSE Maths Proof for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build fluency with number, ratio and algebra first, since geometry, probability and statistics topics rely on them, and leave extra time nearer the exam for Higher-tier problem-solving and multi-step reasoning questions.
