Mathematics plays a key part in every quantitative and theoretical study, and is taught to all science and engineering students to varying degrees at college. Together with its companion volume, Foundations of Science Mathematics(Oxford Chemistry Primer 77), this book bridges the gap between high school and university-level maths. This book provides solutions to most of the problems set in the companion volume. It aims to bolster the reader's practical confidence by providing model answers, and additional comments, for a broad range of exercises. The informal tutorial style adopted in the principal text has been maintained, which will make it accessible to the novice; also, its very concise nature makes it a useful reference for the experienced professional.
