**Index.**

- An introduction to the use of financial tables – mainly web based
- A new section on manipulating equations and formulae
- Now in 2-colour with improved page design
- Improved and updated online supplementary material for both students and lecturers.

- Assumes little in the way of prerequisites but also provides a sound preparation for more advanced work.
- Building up gently from a low level, the author provides a clear, systematic coverage of the key mathematical subjects required by those studying Economic or Business.
- All methods are illustrated by well-chosen examples and exercises.
- The book’s careful arrangement enables it to be used in a variety of course formats – for students with and without prior knowledge of the subject – as well as for reference and self-study.
- Clear Indications of which sections are “essential” and which are “further studies/applications”.
