Kaṇakkusāraṃ is a comprehensive treatise in Manipravalam (a hybrid language which combines Sanskrit lexicon and Malayalam morpho-syntax), composed in the 16th-17th century CE, dealing with elementary arithmetic and methods for solving arithmetical problems arising in the everyday life of members of an agricultural community.
In comparison, Yuktibhasha, composed in pure Malayalam and published in the middle of the sixteenth century, is an advanced text on mathematics and astronomy addressed to the advanced students and scholars of mathematics.
Both have been published by Government Oriental Manuscript Library, Madras (Chennai) in 1950 critically edited with introductions by C. Achyutha Menon.
According to Achyutha Menon the versions are likely to be of different authorship though both might have borrowed material from a common source.
However, at the time of publication of the work by Government Oriental Manuscript Library, the editor of the book C. Achyutha Menon divided it into chapters based on the nature of contents.
