The Republic of India is a South Asian country known for being the second most populous country in the world. India's cuisine, spices, arts and literature, textiles, theater (Bollywood) and much more have all contributed to the world. However, her contributions to mathematics, ranging from antiquity to the present day, are among her most significant. In the world of mathematics, Indian geniuses made revolutionary changes as well as advances and specializations. So it's important that we recognize the contributions of these 15 most famous Indian mathematicians and learn more about what they have done for us!

**1.Brahmagupta**

This polymath is another well-known Indian mathematician, known worldwide for his contributions to the fields of geometry and number theory. His most significant contribution was his recognition of zero as a number, which was a novel concept in ancient mathematics. He laid down all the rules and conventions surrounding the use of zero as a number. His groundbreaking revolution led to the development of today's form of the mathematical number system. He proved Brahmagupta's theorem for cyclic quadrilaterals, a great discovery of his time.

**2. Srinivasa Ramanujan**

Ramanujan, the math genius, taught himself math after failing English in high school. His contributions to analytical number theory, elliptic functions, continued fractions and infinite series are well known. On his set of 120 theorems, which he sent to Cambridge, he was also invited to England. He taught a more important lesson that failure doesn't last because he didn't let his failure discourage him and instead continued to teach himself math, which he loved. Many mathematicians, not only in India but around the world, were inspired by him.

**3. Aryabhata**

Aryabhatta is a name to remember from ancient India as an unsurpassed teacher of great knowledge. Math, astronomy, and science were just some of the subjects he was well versed in. He wrote the "Aryabhatiya", a comprehensive treatise covering a wide range of integral subjects in mathematics such as trigonometry and algebra. He was the first to give an approximation of the value of pi and to do various other mathematical derivations. His contribution to mathematics as the founder of the number system was unparalleled and he is therefore included in our list of the most famous Indian mathematicians.

**4. Bhaskaras**

Bhaskara is a well-known Indian mathematician from ancient times. Bhaskara was both a revered astronomer and a doyen of mathematics. He made important discoveries in both areas. To make life easier and more scientific, he delved into the number system and came up with simple formulas for squaring and multiplying numbers. His work had a significant impact on the development of the number system over time. A creator at heart, Bhaskara is credited with laying the foundations of mathematics in India through his significant work.

**5. PC Mahalanobis**

Prasanta Chandra Mahalanobis, known as the "Father of Indian Statistics", is a well-known Indian mathematician whose contributions to the field of statistics are legendary. His contribution to statistics, which includes developing the concept of pilot and large-scale surveys, has placed him among India's greatest mathematicians. The Mahalanobis model was also used in the second five-year plan, which focused on industrialization. P.C Mahalanobis, also known as the "Father of Indian Statistics", founded the Indian Institute of Statistical Science. June 29 is declared National Statistics Day in his honor, in recognition of his outstanding contributions to statistics as an important branch of mathematics.
