Throughout the book, you will encounter worked examples and a host of rigorous exercises. The examples show you the important techniques required to tackle questions. The exercises are carefully graded, starting from a basic level and going up to exam standard, allowing you plenty of opportunities to practise your skills. Together, the examples and exercises put maths in a real-world context, with a truly international focus.

At the start of each chapter, you will see a list of objectives that are covered in the chapter. These objectives are drawn from the Cambridge AS and A level syllabus. Each chapter begins with a Before you start section and finishes with a Summary exercise and Chapter summary, ensuring that you fully understand each topic. Each chapter contains key mathematical terms to improve understanding, highlighted in colour, with full definitions  provided in the Glossary of terms at the end of the book.

The answers given at the back of the book are concise. However, when answering exam-style questions, you should show as many steps in your working as possible. All exam-style questions, as well as Exam-style papers 2A, 2B, 3A and 3B, have been written by the authors.
