…0313232008 and ISBN-13: 978-0313232008, but way too expensive (I thought the one I read was paperback). Wikipedia describes it at: http://en.wikipedia.org/wiki/Trachtenberg_system which also mentions "Vedic mathematics," http://en.wikipedia.org/wiki/Swami_Bharati_Krishna_Tirtha%27...

Anyway, the source the linked article cites is http://www.vedicsciences.net/articles/vedic-mathematics.html which notes It must be pointed out that these sutras given by Tirtha Maharaja are created by the author himself, as stated in the introduction to his book, "Vedic Mathematics" (published posthumously)…
on “The Sanskrit verse for the value of pi” ↗The verse 'gopi bhagya' basically follows Katapayadi system[0]. Earliest known usage of Katapayadi system was in 683 AD. That verse is from a 1965 book called "Vedic Mathematics" by Bharati Krishna Tirtha Maharaja[1]. The Quora blog you linked has issues with terminologies and timelines of this specific "Vedic Mathematics" book - such as calling these mental calculation techniques…
on “The Sanskrit verse for the value of pi” ↗Yes, indeed. It is mentioned in the wikipedia link ("गोपीभाग्यमधुव्रात..."). I first read it in the "Vedic Mathematics" book by HH Bharati Krishna Tirtha Swamiji. Since he didn't give any attribution, I suppose he was the first one to reveal it.

(I think I first saw this convention with the "vinculum" in Swami Bharatikrishna Tirtha's book Vedic Mathematics which is simultaneously a work of fraud and genius: the book contains several such dazzling tricks that are convenient in special cases, which the Swami must have collected/invented and mapped to a small…
on “Early Times (Multiplication)” ↗This is quite a long read, but I read the first part "Introduction to Vedic Mathematics", and as blown away at the methods of recitation used in ancient Indian to preserve sacred hymns. From what little I've read about Vedic Mathematics, it seems like a powerful way of simplify arithmetic…
on “Vedic Mathematics: Division By The Paravartya Method” ↗LOL! You do realize it's from a book titled "Vedic Mathematics", and not from the Vedas itself? Do you? Did you actually check link at the top of the article linked by OP[1]? And, why do think it's bullshit? I don't see anything wrong in the "Vedic Mathematics"…
on “The Sanskrit verse for the value of pi” ↗…issue, but now I'm working full time and well my learning environment is noisy. Were I to be given another shot at learning math knowing what I know now, I would have first found a way to learn learn Vedic Mathematics so that I don't have to waste so much brain cells on intermediate steps when solving math problems and second, I would have concentrated on learning Technical Mathematics with Calculus and Linear Algebra…
on “Ask HN: How to learn math from zero for adults?” ↗It is sad how much of the knowledge was destroyed due to ideology and religious fanaticism. I have a book here next to me with the title "Vedic Mathematics". The book is based of ancient Indian text. Reading the preface of the book it is clear that what is written in the book is just a small portion of a very large volume of work that was lost. It is sad…

It is at least 20 years old, I still have my copies that I received in 2001 as a gift, Amazon says it was published in 2019 which is incorrect; it is far older. It was often used alongside activities…
