Bijaganita is a branch of mathematics that focuses on algebra and its applications. The term translates to "the science of calculation" in Sanskrit and is primarily associated with ancient Indian mathematicians. It encompasses various concepts, including equations, geometric figures, and numerical calculations. The most notable figure in Bijaganita is Brahmagupta, a 7th-century mathematician who made significant contributions to algebra. His work included rules for solving quadratic equations and methods for calculating areas of geometric shapes. Bijaganita laid the groundwork for future developments in mathematics, influencing both Indian and global mathematical traditions.
