This book aims to ensure students not only overcome their fear of numbers but befriend them. The book provides ample opportunities to play with numbers as it teaches how to solve a problem in multiple ways, in contrast to the rigid conventional system where students have to rely only on one method.

Overall, they find it fun. Vedic methods are very simple yet extremely powerful. They show us how to solve complicated problems mentally and quickly with ease. No wonder, with practice, the so-called 'weak' and 'slow' students transform into smart ones within months, which proves the effectiveness of the Vedic system.The book contains 120 lessons on topics from arithmetic and algebra, 300+ examples with explanations for conceptual clarity and 4000+ questions for practice. Each lesson comes with super-fast mental calculation techniques. Written in simple language, it is a self-learning book for teachers and students of grades 6 to 12.
