Accessible, concise, and interactive, this book introduces the mathematical methods that are indispensable in economics and finance. Fully updated to be as student friendly as possible, this edition contains extensive problems, worked examples and exercises (with full solutions at the end of the book). Two brand new chapters cover coupled systems of recurrence/differential equations, and matrix diagonalisation. All topics are motivated by problems from economics and finance, demonstrating to students how they can apply the mathematical techniques covered. For undergraduate students of economics, mathematics, or both, this book will be welcomed for its clarity and breadth and the many opportunities it provides for readers to practise and test their understanding.

• Uses an economic or financial problem to motivate each mathematical topic, showing students how they will use the techniques in practice
• Provides ample opportunities for students to practise problem-solving and test their understanding, with worked examples, exercises and problems in every chapter
• Fully class-tested at LSE by the authors
• Covers the material in digestable, clearly discrete (but connected) components, making it easy to construct a study timetable and to confirm understanding of each section before progressing
