Who Invented Zero?

[Still Waters]

Though humans have always understood the concept of nothing or having nothing, the concept of zero is relatively new — it only fully developed in the fifth century A.D. Before then, mathematicians struggled to perform the simplest arithmetic calculations. Today, zero — both as a symbol (or numeral) and a concept meaning the absence of any quantity — allows us to perform calculus, do complicated equations, and to have invented computers.
