Talk about the contribution of Indians to the field of Mathematics and the name of the famous scholar, Aryabhata would be the first thing to strike your mind. He was one of the first mathematicians from the classical age to contribute immensely to the field of mathematics. He worked on the place value system by using letters for signifying numbers and stating their qualities. Besides, this great mathematician also calculated and mentioned the exact number of days in a year.
Not just Aryabhata, there have been several Indians who have contributed majorly to this field.
Mathematics has a mention even in our Vedic literature which means in India it has been a subject of interest since the last 4000 years. In between 1000 BC and 1000 AD, several treaties had been authored by different Indian mathematicians in which the concept of zero, rudiments of geometry, square and cube root and the techniques of algorithm and algebra were brought forth. The introduction of zero is said to be one of the major contributions by Indians. It was the learned mathematician Brahmagupta who introduced the concept of zero. He taught the rules of using zero with both positive and negative numbers.
Apart from this many other Indians also studied this field extensively and came up with various mathematical theories such as algebra of inequalities, continued fractions, theory of estimation, products of hypergeometric series, elliptic functions, infinite dimensional group representation and quantum mechanics among others.
C.R. Rao, Srinivasa Ramanujan, D. R. Kaprekar, Satyendranath Bose, P.C. Mahalanobis, Narendra Karmarkar and Harish Chandra are some of the Indian mathematicians who are known for putting forward the aforementioned theories.
