Have you ever heard of Vedic Mathematics? It's an ancient system of math from India that was re-discovered in the early 1900's. From what I understand this is the system of math that is taught throughout India today.

I just bought the book,Vedic Mathematics, by Sri Bharati Krsna. I'm still only beginning to learn this system of math, but so far it is certainly far more efficient than the mathematics taught in the West. Here is a good tutorial of it. http://www.vedicmaths.org/Introducti...l/Tutorial.asp
