Q: Which Indian mathematician is credited with the first formal use of zero as a number?

Brahmagupta (628 CE, in the Brāhmasphuṭasiddhānta).. Before him, zero was a placeholder. He gave it rules — added it, subtracted from it, divided by it (and got it spectacularly wrong, but he tried). Mathematics has never been the same.
