Brahmagupta

Brahmagupta

Brahmagupta is the discoverer of zero. He lived from 597 A.D. to 668 A.D. He was a Ancient Indian astronomer and mathematician. Brahmagupta wrote four books in his time. He found out that the Earth is closer to the moon than the sun. Brahmagupta is most famous for his books and that is where a lot of his research can be found. Though he discovered zero, he thought zero divided by zero equals zero. However he did believe in negative and positive numbers.
