Explanation

Brahmagupta (7th century CE) was the first to treat zero as a number and establish rules for arithmetic operations with zero in his Brahmasphutasiddhanta (628 CE). He defined zero as a number (not just a placeholder) and explained operations like addition, subtraction, multiplication, and division involving zero. While Aryabhatta used zero as a placeholder, Brahmagupta was the first to treat it as an actual number with mathematical properties.
