Number — IGCSE Mathematics - International (0607) questions by topic
Number questions cover a wide span: taking a cube root, combining two given ratios into a single three-part ratio, rounding a value to the nearest hundred, and completing a table linking consecutive integers to counts, so both arithmetic accuracy and pattern recognition are tested.
Work out, find, calculate, write and state lead the command words, worth from 1 to 10 marks, reflecting 70 questions set in 2025 papers, the second-largest set on the page. Because ratio and rounding questions are easy to rush, practise each calculation slowly and check units or precision before moving on, then use instant marking to catch a rounding slip or reversed ratio order immediately rather than losing marks silently across the paper.
