Brahmagupta was the first person to formalize arithmetic operations using zero. He placed dots under numbers to represent zero, calling them "sunya," which means empty, or 'kha," which means place. He also wrote the standard rules for reaching zero through addition and subtraction, as well as the results of any operations with zero. It would take until 879 A.D. for the number zero to make it to Europe and become the oval shape used today.
