Manuscripts (e.g., "Bijaganita")

Manuscripts like "Bijaganita" are ancient handwritten books that contain mathematical knowledge. "Bijaganita," meaning "algebra" in Sanskrit, is an early Indian mathematical text that explores concepts like equations, variables, and calculations. These manuscripts often include detailed explanations, problem examples, and methods for solving mathematical questions. They serve as valuable historical records showing how mathematicians of the time understood and developed math, laying the foundation for modern algebra and arithmetic. Preserved over centuries, such manuscripts provide insight into the evolution of mathematical thought across cultures and eras.
