Bhaskara II or as Bhaskaracharya, this latter name meaning "Bhaskara the Teacher". In many ways He represents the peak of mathematical knowledge in the 12th century. He reached an understanding of the number systems and solving equations which was not to be achieved in Europe for several centuries.

Bhaskara II`s father was a Brahman named Mahesvara. Mahesvara himself was famed as an astrologer. Bhaskara II became head of the astronomical observatory at Ujjain, the leading mathematical centre in India at that time. Outstanding mathematicians such as Varahamihira and Brahmagupta had worked there and built up a strong school of mathematical astronomy. His mathematical works were the first to make full and systematic use of the decimal system. He evidently was the first to gain some understanding of the meaning of division by zero. He used letters to represent unknown quantities, much as in modern algebra, and solved indeterminate equations of 1st and 2nd degrees. He wrote on his astronomical observations of planetary positions, conjunctions, eclipses, cosmography, geography, and the mathematical techniques and astronomical equipment used in these studies.
