Answer:
Bhaskara's probably most important mathematical contribution concerns the representation of numbers in a positional system. The first positional representations had been known to Indian astronomers approximately 500 years prior to this work. However, these numbers, prior to Bhaskara, were written not in figures but in words or allegories and were organized in verses. For instance, the number 1 was given as moon, since it exists only once; the number 2 was represented by wings, twins, or eyes since they always occur in pairs; the number 5 was given by the (5) senses. Similar to our current decimal system, these words were aligned such that each number assigns the factor of the power of ten correspondings to its position, only in reverse order: the higher powers were right from the lower ones.
His system is truly positional since the same words representing, can also be used to represent the values 40 or 400.[6] Quite remarkably, he often explains a number given in this system, using the formula ankair api ("in figures this reads"), by repeating it written with the first nine Brahmi numerals, using a small circle for the zero . Contrary to his word system, however, the figures are written in descending values from left to right, exactly as we do it today. Therefore, at least since 629, the decimal system is definitely known to the Indian scientists. Presumably, Bhaskara did not invent it, but he was the first having no compunctions to use the Brahmi numerals in a scientific contribution in Sanskrit.

Explanation:
Bhaskar (Bhaskaracharya) was a famous mathematician. Mathematicians in Asmaka which was probably in the Nizamabad District of Andhra Pradesh. There are other references to places in India in Bhaskara's writings. There are some allusions to Valabhi , the capital of the Maitraka dynasty in the 7th century, and Sivarajapura, which were both in Saurashtra, which today is the state of Gujarat. There is yet another school of thought which believes that he was born in Bori, in Parbhani district of Maharashtra. By and large, it is believed that Bhaskara was born in Saurashtra and later moved to Asmaka. It is believed his father taught him astronomy. Bhaskara is considered to be a follower of Aryabhata. He is considered to be the most important scholar of Aryabhata's astronomical school.
