This comprehensive text is specifically written for further education students taking GCSE mathematics. It is intended to provide a source which is acceptable to more mature students tackling GCSE for the first time or, more particularly, those retaking to improve their grade. The text introduces all topics from scratch so no previous standard is required. It covers the new GCSE examination syllabuses published in 1992, and is the first FE GCSE mathematics text aligned with the National Curriculum GCSEs. The mathematical arguments are frequently annotated to help explain what is going on. The book also: covers all material up to and including Level 8 of the National Curriculum (GCSE Grade B); is targeted specifically at intermediate-level students; relates to mature students' interests in work, leisure, society and the media; includes answers to all exercises; and includes sample GCSE test papers.
