Various of my Mathematics teachers and instructors have guided me to go for Vedic Mathematics for "lightning fast calculations". It is said that this is a traditional method, which needs lots and lots of practice. But if you are able to grasp it, calculations of roots and powers are as simple as addition and subtraction! I have been trying to get a book on it, but I have been unable to get one.
Have you gone through that? Any ideas or guess over how it really is?
