Step-by-step lessons covering Oxford AQA IGCSE Maths Addition and Subtraction for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
