[3] This commentary, Āryabhaṭīyabhāṣya, written in 629, is among the oldest known prose works in Sanskrit on mathematics and astronomy.
[3][4] On 7 June 1979, the Indian Space Research Organisation launched the Bhāskara I satellite, named in honour of the mathematician.
Also mentioned are Bharuch in southern Gujarat, and Thanesar in the eastern Punjab, which was ruled by Harsha.
Therefore, a reasonable guess would be that Bhāskara was born in Saurastra and later moved to Aśmaka.
[1][2] Bhāskara I is considered the most important scholar of Aryabhata's astronomical school.
He and Brahmagupta are two of the most renowned Indian mathematicians; both made considerable contributions to the study of fractions.
The most important mathematical contribution of Bhāskara I concerns the representation of numbers in a positional numeral system.
The first positional representations had been known to Indian astronomers approximately 500 years before Bhāskara's work.
Contrary to the word system, however, his numerals were written in descending values from left to right, exactly as we do it today.
Presumably, Bhāskara did not invent it, but he was the first to openly use the Brahmi numerals in a scientific contribution in Sanskrit.
In 629, he annotated the Āryabhaṭīya, an astronomical treatise by Aryabhata written in verses.
Bhāskara's comments referred exactly to the 33 verses dealing with mathematics, in which he considered variable equations and trigonometric formulae.
In general, he emphasized proving mathematical rules instead of simply relying on tradition or expediency.
