: "The earliest number symbols were in India. In 3000 BC the Hindus culture was using large numbers. From the middle of 2000 BC these tribes spread towards India. They introduced Sanskrit which was the earliest knowledge of math at that time. In Sanskrit there are number words for 1-9, 10, 100 and higher powers of ten.
From about 3 BC Brahmi numbers and inscriptions have been found all over India. "
