What is it
GCSE Number covers working confidently with all types of number — integers, fractions, decimals, percentages, standard form, and rounding — including the non-calculator methods examiners expect you to know by heart.
Why it matters
Number sits underneath every other GCSE maths topic — a shaky grasp of fractions or standard form quietly costs marks in algebra, geometry and statistics questions that assume these skills are already solid.
Exam tip
Practise non-calculator arithmetic regularly, not just calculator methods — the non-calculator paper specifically tests whether these skills are truly automatic, not just achievable with time.
