Query: A great basic reference book for Pure Mathematics

This was a core text for many British A-Level Mathematics students. It is a well written and easy to follow text book. The major flaw in an otherwise super text is that it has several typos and the occasional incorrect answer to self-test questions. These errors can hinder a student's understanding of a concept.However, over a decade and a half after completing my A-level studies I still refer to this text when helping students grasp pure math concepts.
