Aryabhata is widely recognized as the 'Father of Indian Mathematics' for his significant contributions to astronomy, mathematics, and trigonometry.

Brahmagupta, a renowned Indian mathematician, is credited with introducing the concept of zero as a number and developing the decimal system.

Baudhayana, an Indian mathematician who lived around 800 BC, discovered the Pythagorean theorem long before Pythagoras.

Pingala, an Indian mathematician and grammarian, is credited with developing the Fibonacci sequence centuries before Fibonacci.

Brahmagupta was the first mathematician to develop the concept of negative numbers and establish rules for their operations.

Bhaskara II, also known as Bhaskaracharya, made significant contributions to trigonometry, including the development of trigonometric formulas and identities.

Srinivasa Ramanujan, a self-taught Indian mathematician, made remarkable contributions to the field of calculus, including the development of new theorems and formulas.

Aryabhata is credited with developing the concept of the 'zero matrix', which is a square matrix with all elements equal to zero.

Bhaskara II developed the concept of the 'continued fraction', which is a way of representing a number as an infinite sum of fractions.

Srinivasa Ramanujan made significant contributions to number theory, including the discovery of new properties of prime numbers and the development of new methods for solving Diophantine equations.

Brahmagupta developed the concept of the 'magic square', which is a square grid of numbers where the sum of each row, column, and diagonal is the same.

Bhaskara II developed a version of the 'binomial theorem', which is a formula for expanding the power of a binomial.

Aryabhata developed the concept of the 'LCM' (Least Common Multiple) and 'HCF' (Highest Common Factor) of two or more numbers.

Brahmagupta made significant contributions to algebra, including the development of new methods for solving quadratic equations and the introduction of negative numbers.

Pingala developed the concept of the 'Pascal's triangle', which is a triangular array of binomial coefficients.
