The total number of verses in this text is 214. The Laghu-
Bhāskarīyam is thus an abridged edition of the Mahā-Bhāskarīyam.
From the closing stanza of this work, it is clear that the author
wrote this work for the benefit of young students with immature
mind by condensing and simplifying the contents of his larger
work, the Mahā-Bhāsarīyam (also known as Karma-nibandha).
Thus we have a little of the parallelism: Brahmagupta, after
finishing his bigger treatise, the Brahma-sphuṭasiddhānta, wrote
a minor abridged work, the Khaṇḍa-khādyaka, as a karaṇa
grantha. This latter work of Brahmagupta, however, incorporates
some original ideas not included in the earlier work. Shukla
has given an analytical table indicating the rules of the Mahā-
Bhāskarīyam incorporated in the Laghu-Bhāskarīyam also in an
abridged or modified form, and also a list of the rules which have
been omitted in the Laghu-Bhāsakrīya. There are a few rules
in the Laghu-Bhāskarīya also which have no counterpart in the
