# Essential Mathematics for Cambridge Secondary 1: Stage 8

The Essential Mathematics for Cambridge Secondary 1 series has been created for the international student. Written by an expert author team with an experienced examiner, it provides complete coverage of the latest Cambridge syllabus. The Student Book contains comprehensive coverage of the curriculum framework content and provides engaging exercises that promote problem solving and investigative strategies. Inclusion of summary and review sections after each topic

help students retain learning, while Checkpoint-style questions assist their preparation for assessment. Learning Outcomes are provided at the start of each chapter to clearly map topics in the text to the syllabus. Numerous exercises are included, with clear progression, and problem-solving and real

life applications embedded throughout. Helpful hints throughout the text guide students and remind them of the key pieces of information required.
