Mathematics in Ancient India made significant contributions, particularly in the fields of arithmetic, geometry, and algebra. The ancient Indian mathematicians developed the concept of zero and the decimal system, which are fundamental to modern mathematics. Notable texts, such as the Aryabhatiya by Aryabhata, laid the groundwork for mathematical principles and calculations. Additionally, the Sulbasutras, ancient texts on geometry, provided rules for constructing altars and other structures. These texts included methods for calculating areas and volumes, showcasing advanced understanding of geometric principles. The work of mathematicians like Brahmagupta further advanced algebraic concepts, influencing mathematics for centuries to come.
