What r the treatises written by aryabhatta

Mathematical Work. Aryabhata wrote many mathematical and astronomical treatises. His chief work was the 'Ayrabhatiya' which was a compilation of mathematics and astronomy. The name of this treatise was not given to it by Aryabhata but by later commentators.

Aryabhata (IAST: Āryabhaṭa) or Aryabhata I[2][3] (476–550 CE)[4][5] was the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His works include the Āryabhaṭīya (499 CE, when he was 23 years old)[6] and the Arya-siddhanta.

The Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathmatics and astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita(“Mathematics”), Kala-kriya (“Time Calculations”), and Gola (“Sphere”).
