It spans the full range of students' abilities with a large number of questions that are carefully graded and range from quite easy to more demanding. They will provide sufficient work for students of every ability taking the course. The gradual changes of emphasis in HSC examinations over the last ten years have been carefully addressed by the authors. The authors also encourage mathematical imagination through careful exposition and interesting questions, and by relating the various topics. Chapters are systematically divided into manageable sections which consist of a substantial exercise preceded by theory and worked examples. The exercises are then divided into three groups: Group 1 for more straightforward algorithms, Group 2 for harder algorithms and Group 3 for problems that link to other topics.
