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.

Brahmagupta’s work Revision of the System of Brahma (628), a significant part of which is devoted to arithmetic and algebra, has come down to us.
