Maths Made Easy by Dexter J Booth
This book is aimed at students who are entering further and higher education and need to acquaint themselves with elementary mathematics or reacquaint themselves with mathematics that they might have learned a little while before and forgotten. It is written assuming virtually no previous knowledge beyond the ability to count and it has an easy conversational style.
The text has copious amounts of worked examples and end-of-chapter exercises, which will enable you to test your understanding of the material. Answers to selected exercises are provided.
