The use of zero, or '0', was first used by the Babylonians around 300 BC, as a placeholder, like the '0' in '10' or '100'. The oldest known reference to zero as a numerical value to signify 'nothing' was by the Indian mathematician and astronomer Brahmagupta, in his great work of 628 AD, the Brahmasphutasiddhanta.
