Significant figures are used to show an appropriate level of accuracy in measurements and calculations, and they come up a lot in GCSE Maths and science subjects. We focus on: • What counts as a significant figure (including tricky zeros) • How to identify the first significant digit in any number • Rounding to 1, 2, 3 (or more) significant figures • Writing rounded answers clearly and correctly • How significant figures link to measurements, estimation, and bounds • Common mistakes students make — and how to avoid them 👍 Like • 💬 Comment what to cover next • ✅ Subscribe for more maths revision
