Justify - GCSE Maths Definition

In GCSE Maths, to "justify" means to explain or prove why an answer or method is correct using logical reasoning and evidence. When you justify your answer, you need to show your working out and the steps you took to arrive at your conclusion. This can include using mathematical rules, calculations, diagrams, or examples to back up your statements.

Justifying an answer helps to show your understanding of the topic and ensures that the solution makes sense. It's not just about getting the right answer, but about showing why the answer is right.
