fascinating mathematics -- part 2

wow i did a quick google search on the video below, and turns out this is actually based on a mathematical system called Vedic Mathematics.

apparently, "Vedic mathematics is a system of mathematics consisting of a list of 16 basic sutras, or aphorisms, that allegedly encompass all mathematics. They were presented by a Hindu scholar and mathematician, Jagadguru Swami Sri Bharati Krishna Tirthaji Maharaja, during the early part of the 20th century (Trivedi, 1965)."
