"There are plenty of books available in the market on faster calculations but more often than not the authors of such books had not tested the techniques they propound and promote in real life problem solving situations. However, the techniques that you shall find in this book have been tested and used (not only by the author but by countless other people) in examinations time and again.

Many techniques mentioned in other books are pretty impractical and sometimes completely unusable. This book is not a package of magic. It is rather a package of methods that if practiced and persevered with can churn up magical results! This book could be a great resource for various competitive examinations and students in middle and senior school. It could help the reader in myriad ways depending upon his or her needs and scope for practice. At the same time one could figure out as to which technique would work for one and which would not, again depending upon one’s set of circumstances and needs. By reading this book, the students will be able to:

• learn quicker methods by observing some simple techniques;

• compare various techniques available on each topic;

• know the limitations of each technique;

• save some precious minutes in various competitive and school examinations by employing the quick calculation techniques;

• develop their own tools in the field of quick calculations."
