A celebrated astronomer and mathematician, Bhāskarācārya (A. D. 1114-1160) wrote the monumental work Siddhānta-śiromaṇi when he was only 36. It has four chapters of which the first—called Līlāvatī—is on arithmetic. The story goes that he named this part of his work after his daughter Līlāvatī who was widowed at an early age, to immortalize her. An extremely popular work written in an interesting and entertaining manner, it has been translated into several languages over the centuries. It includes sections on śūnya or zero, geometry, mensuration, and kuṭṭaka or indeterminate equations of the first magnitude. Bījagaṇita or algebra is the second chapter. The other two chapters called Gaṇitādhyāya and Golādhyāya are works on astronomy that include celestial mathematics.

The work has several commentaries in Sanskrit.

Another work of his, called Kāraṇa-kutūhala, a handbook for preparing astronomical tables, is not so well-known.
