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”.
