Vedic Maths

This series will cover various topics/techniques covered under Vedic Maths. Vedas are very old scriptures of Hinduism. Mathematical methods in Vedas were lost in time, they were rediscovered by Bharati Krishna Tirthaji.

Bharati Krishna Tirthaji

Vedic Maths includes various methods/concepts that make mathematical calculations simple. When I was a kid my Dad had presented me a book written by Bharati Krishna Tirthaji. I could not understand much then but my curiosity remained. Recently I bumped into book "Power of Vedic Maths" by Atul Gupta. Author has gone through various methods of Vedic Maths in comprehensive and illustrious way. I would highly recommend this book. My idea here is to explore and explain each method in detail and verify it mathematically. I would not try to explain the Vedic Maths sutra's and their translation, which I leave it to readers.I would be more than happy to hear your feedback.

Following books are highly recommended
1. Vedic Maths by Atul Gupta
2. How to become a Human calculator by Aditi Singhal

Happy Learning
