It is now generally accepted by all that the study of Economics is incomplete without knowledge of Mathematics. There are many excellent text book on Mathematical Economics written by Foreign as well as Indian author. However, most of these books are above the stander of an average students. Hence this book is mainly written for the beginners. This book is the outcome of my own actual classroom experience. The main aim in writing this book is precise and concise exposition of the principles, method and techniques of Mathematics. Another main objective of the book is the lucid style and simplicity of expression. Solved examples are added at the end of each chapter to make the students familiar with the subject.
