Algebra — IGCSE Mathematics - International (0607) questions by topic

Algebra is the biggest topic on the page: simplifying algebraic fractions, expanding triple brackets, rearranging a formula for safe office occupancy, and setting up simultaneous equations from a growth model all fall under this heading, spanning single-step manipulation to multi-stage problems.

Find, complete, show, calculate and work out lead the command words, worth anywhere from 1 to 19 marks, reflecting 75 real questions drawn from 2025 papers. Because a single slip in expanding brackets can cascade through a long question, practise each stage of simplification separately, then submit your working for instant marking so a sign error or missed term is caught on that line rather than at the final answer.
