Brahmagupta was a practicing Hindu and a Shaivite. He was the author of Brahmasphutasiddhanta and Khandakhadyaka – both works that discussed mathematics and astronomy – with the former being a theoretical treatise while the latter covers a more practical approach. With this article, we bring you facts about Brahmagupta, one of the most significant mathematicians to have been born in India.


Brahmagupta wrote Brahmasphutasiddhanta at the age of 30, a revised version of the Siddhanta of Brahmapaksha school of Astronomy where he was an astronomer. In the book, Brahmagupta has composed 24 chapters with 1008 verses in Arya metre. Most of the book deals with astronomy, however, it also includes chapters on mathematics that discuss trigonometry, algebra, geometry, etc. He composed Khandakhadyaka much later – at 67 – after he had moved to Ujjain, which was a major hub for studying astronomy in India. This text was meant to be a manual for students of astronomy. 

Over the years, Brahmagupta came up with key findings that were significant in the progress of mathematics and astronomy. With that, we bring you these facts about Brahmagupta to shed light on the many mathematical discoveries credited to the genius of Brahmagupta.
