Vedic Addition by Vikram Devatha
Vedic Mathematics is a system of mathematics that allows problems to be solved quickly and efficiently. It is based on the work of Sri Bharathi Krishna Thirthaji Maharaja (1884 – 1964), who devised the system from a close study of the Vedas. It is based on 16 sutras (aphorisms) that provide a principle or a rule of working to solve a problem.
This series of books is an attempt to present the material in a modular fashion. Each book focuses on one arithmetic operation – addition, subtraction, multiplication and division. These books can be read in any order, but it is recommended that addition and subtraction be read before multiplication and division. This particular book is related to addition only, and subsequent books will cover the other arithmetic operations.
The book features screencasts that explain each technique, visuals and interactive exercises.
