He wrote in verse the Brahma-sphuta-siddhanta [improved system of Brahma], a standard work on astronomy containing two chapters on mathematics that were translated into English by H. T. Colebrooke in Algebra … from the Sanskrit of Brahmagupta (1817). A shorter treatise, The Khandakhadyaka (tr. 1934), expounded the astronomical system of AryabhataAryabhata, c.476–550, Hindu mathematician and astronomer.
