One main Indian innovation that is used throughout the world is the number zero. Indian mathematicians were the first to recognise and use zero as a real number. About 500BCE Indian scholar Pingala used the sanskrit word śūnya to represent zero. In 498CE Aryabhata developed a ten digit decimal notation system that is the basis of our 0,1,2,3,4,5,6,7,8,9, system today.
