In ancient India, mathematical knowledge was preserved through a combination of oral tradition, written texts, and inscriptions on stone or metal.

Vedic hymns, Upanishads, and Sutras are all examples of oral traditions used to preserve mathematical knowledge in India.

Sulba Sutras, Aryabhatiya, and Lilavati are all examples of written texts used to preserve mathematical knowledge in India.

Yupa inscriptions of King Ashoka, inscriptions at Khajuraho, and inscriptions at Konark are all examples of inscriptions used to preserve mathematical knowledge in India.

Gurukulas, temples, and courts all played a significant role in the preservation and transmission of mathematical knowledge in India.

Gurukulas played a multifaceted role in the preservation and transmission of mathematical knowledge in India, encompassing formal education, research, and library services.

Temples played a multifaceted role in the preservation and transmission of mathematical knowledge in India, encompassing learning, financial support, and patronage.

Courts played a multifaceted role in the preservation and transmission of mathematical knowledge in India, encompassing patronage, commissioning, and facilitation of knowledge exchange.

Aryabhata, Bhaskara II, and Brahmagupta are all examples of mathematicians who played a significant role in the preservation and transmission of mathematical knowledge in India.

Aryabhata made significant contributions to the preservation and transmission of mathematical knowledge in India, including the development of positional notation, the introduction of zero, and the authorship of the Aryabhatiya.

Bhaskara II made significant contributions to the preservation and transmission of mathematical knowledge in India, including the authorship of Lilavati, the development of new methods for solving quadratic equations, and advances in trigonometry.

Brahmagupta made significant contributions to the preservation and transmission of mathematical knowledge in India, including the authorship of Brahmasphutasiddhanta, the development of new methods for solving indeterminate equations, and advances in astronomy.

Sulba Sutras, Aryabhatiya, and Lilavati are all examples of mathematical texts that played a significant role in the preservation and transmission of mathematical knowledge in India.

The Sulba Sutras were significant in the preservation and transmission of mathematical knowledge in India as they provided instructions for constructing altars and other religious structures, contained mathematical knowledge related to geometry and trigonometry, and were used to teach mathematics to students in Gurukulas.

The Aryabhatiya was significant in the preservation and transmission of mathematical knowledge in India as it was the first mathematical text to use the decimal system, introduced the concept of zero as a number, and contained a comprehensive treatment of astronomy and mathematics.

The Lilavati was significant in the preservation and transmission of mathematical knowledge in India as it was a popular textbook for teaching mathematics to students, contained a wide range of mathematical topics, and was written in a clear and accessible style.
