recent surveys of NCERT show that a majority of students coming out of the school at primary, middle and even secondary level are so dependent on the calculator and computer that they are unable to do simple arithmetical calculations without these tools. In a cut- throat competitive world, time is a big constraint. We have to train our brain in such a way that it can do fast calculations quickly. Traditional methods of addition, subtraction, multiplication and division are long and time consuming. The technique and methods of Vedic mathematics are simpler and save a lot of time. For proficiency in their use, we need a bit of theoretical understanding and some practice of the use of simple rules. Rajesh Thakur’s book explains the basic rules, methods and techniques of Vedic mathematics with the help of a large number of illustrative examples.
Vedic formule being one-line phrases are easy to understand and remember. We can use these in solving problems ranging from arithmetic to algebra and from geometry to calculus and trigonometry. Even a layman equipped with the Vedic method can multiply a five into five digit multiplication in less than 20 seconds and that too in a single line. The presentation of an insipid and dry subject like mathematics in this book has converted it into a playful and joyful activitiy, doing away with the maths-phobia which many people often suffer from. The book starts from precise and clear explanation of vedic sutras and sub-sutras. These are followed by separate sections on addition, subtraction, multiplication, division, squares, cubes, roots, powers, factorisation, simltaneous equations, quadratic equations and trigonometry. The comprehensiveness and self-study approach of this book makes it all the more useful to countyer the phobia which many people often suffer from.

Vedic mathematics is the
brainchild of Jagadguru Sankracharya Sri Bharti Krishna Tirthji
Maharaj, who discovered its sutras (formulae) and sub-sutras
between 1911 and 1918. The 16 sutras and an equal number of sub-sutras
were culled out from Vedic literature after an extensive research.
The exact origin of these sutras is debatable but their
practical utility is beyond any doubt. These can create revolutionary
changes in fast calculations. Fast and flawless calculations, with
in-built checks midway can be of great help for students preparing for
CAT, UPSC, NTSE and banking examinations.
