Vedic mathematics is composed of sutras which have been formulated over many centuries by sages of India. the sutras which are in Sanskrit have been lost over the centuries due to neglect of future generations. due to dedicated efforts of a few enthusiasts it is being revived to its previous glory. The pioneer in this field was Jagadguru Swami Sri Bharati Krishna Tirthaji Maharaja, who compiled sixteen sutras and unleashed this wonderful science to the world. He wrote sixteen volumes encompassing some of the greatest Vedic sutras but all were lost and he finally wrote one book explaining the sixteen sutras before he passed away from this world.
The ancient system of Vedic Mathematics was rediscovered from the Sanskrit texts known as the Vedas, between 1911 and 1918 by Sri Bharati Krsna Tirthaji (1884-1960). At the beginning of the twentieth century, when there was a great interest in the Sanskrit texts in Europe, Bharati Krsna tells us some scholars ridiculed certain texts which were headed 'Ganita Sutras'- which means mathematics. They could find no mathematics in the translation and dismissed the texts as rubbish. Bharati Krsna, who was himself a scholar of Sanskrit, Mathematics, History and Philosophy, studied these texts and after lengthy and careful investigation was able to reconstruct the mathematics of the Vedas. According to his research all of mathematics is based on sixteen Sutras, or word-formulae.
Bharati Krishna wrote sixteen volumes expounding the Vedic system but these were unaccountably lost and when the loss was confirmed in his final years he wrote a single book: Vedic Mathematics, currently available. It was published in 1965, five years after his death.
