Vedanga Jyothisa says - "Like the crest of the peacock, like the gem on the head of a snake, so is Mathematics at the head of all knowledge." Indian Mathematicians are numerous - Pingala, Aryabhata, Bhaskara, Brahmagupta, Katyayana, Mahaveeracarya, Madhava, Sreedharacarya, Bharati Krishna Teerthaji Maharaj and so on. Their contributions to the world of Mathematics are lot many - place value system, importance of 'Zero', etc. Vedas and Mathematics are inseparable. It is an integral part of Vedas, which origin is yet to be clearly specified. Hence the origin of Indian Mathematics also cannot be defined. They used different systems to represent numbers - the major three systems are Katapayadi Sankhya, Bhoota Sankhya and Aryabhateeya Sankhya. These system of numbers were used to represent mathematics through poetic words - dual expertise. It is an ocean. This book tries to bring out a drop from this ocean.
