Brahmagupta

Brahmagupta was a prominent Indian mathematician and astronomer who lived around the 7th century CE. He is best known for his work "Brahmasphutasiddhanta," which made significant contributions to arithmetic, algebra, and geometry. He was among the first to use zero as a number and developed rules for calculating with negative numbers. Brahmagupta's insights laid the groundwork for future mathematics and greatly influenced both Indian and Islamic mathematical traditions. His work helped shape the understanding of mathematics, making complex concepts more accessible for later scholars.
