Brahmagupta (c. 597 - 668 AD)
Brahmagupta was the first to use zero as a number, although it had been in use before his time as a symbol, representing the order of magnitude of the number in question (7 - 70 - 700 etc.). Consequently, he devised the rules of arithmetic involving zero. Brahmagupta was also the first to note that the product of two negative numbers is a positive number.
