Indian scholars developed the concept of zero around 320 AD during the Gupta Empire, a period marked by significant advancements in mathematics and astronomy. They recognized zero as both a placeholder in the positional number system and a symbol for the absence of quantity. This innovation facilitated more complex calculations and laid the groundwork for modern arithmetic, influencing mathematical thought globally. The work of mathematicians like Aryabhata further popularized these ideas, solidifying zero's importance in mathematics.
