Bakhshali Scroll is the Oldest use of Number Zero

The origin of zero is still a mystery. The Egyptians used it, and so did Babylonians. However, it was never as a numeral rather more like a place holder. Quite recently, a team of Scientists at University of Oxford Bodleian Libraries, carbon dated one of the famous ancient Bakhshali scroll. The dates come out to third and fourth century A.D. making it one of the oldest recorded use of the number zero.

The scroll has been with Bodleian library since 1902. However, it was excavated from field in 1881 in Bakhshali town (current day Pakistan). It has always been recognized as one of the oldest mathematical text with use of zero several times. But it’s exact date  had remained a mystery since its excavation.
