English for Mathematics is intended for intermediate and higher level students who specialise in mathematics or are simply interested in it. The underlying assumption is that the students who are going to use this book have more than basic knowledge of mathematics. Therefore, our aim is not to explain the obvious to people whose knowledge of the subject is by far more extensive than ours. The book is by no means exhaustive as the authors decided to focus on the issues addressed during the standard graduate course. We hope that the book will give the students a chance to familiarise themselves with vocabulary and idioms associated with mathematical English in the lightest and most entertaining fashion.
