Three works were written by him in the following chronological order: ( i ) *Mahābhāskarīya*², an astronomical work complete in eight chapters, ( ii ) *Āryabhaṭīyabhāṣya*³, a commentary on the *Āryabhaṭīya* of Āryabhaṭa and ( iii ) *Laghubhāskarīya*⁴, an abridged and simplified version of *Mahābhāskarīya* in eight chapters. Bhāskara I was mainly an astronomer but made commendable progress in the solution of the indeterminate equation of the first degree, the method of whose solution is given in his *Mahābhāskarīya*⁵ for use in the solution of astronomical problems⁶. Brahmagupta and others simply adopted the methods of Āryabhaṭa I and Bhāskara I. The method was however improved at a later period by Āryabhaṭa II (c. 950 A.D.) by abridging the operations in certain cases.
