Vedic mathematics is a system of mathematics that was rediscovered from ancient Hindu scriptures called the Vedas between 1911-1918. It is based on 16 sutras or word-formulas and 13 sub-sutras that describe how the mind naturally works. The Vedic system is more coherent and unified than modern mathematics, with techniques that are easy to understand and relate to one another. It allows complex problems to be solved quickly through intuitive and direct methods.
