Table of Contents
The roots of Indian mathematics lie in Vedic literature. Vedic literature is believed to have emerged several thousand years and forms one of the oldest literary traditions in the world.
In India, mathematical ideas developed gradually over several centuries through the contributions of scholars from different periods.
This period includes the concept of zero, the techniques of algebra and algorithms, geometry, and the decimal system.
The Vedic period was a period of history that occurred roughly from 1700 BCE to 150 BCE.
The Sulba sutras, which are known to be the appendices of the Vedas, are the only sources of knowledge of Indian mathematics from this period.
They are guides or handbooks for the construction of sacrificial altars used in Vedic worship. This included geometrical rules related to figures, such as triangles and circles.
India has a rich mathematical legacy that spans thousands of years.
Indian mathematicians have contributed significantly across different historical periods, from ancient scholars who laid the foundations of number systems to modern researchers and pioneers who transformed mathematical research.
Indian mathematicians made early contributions to number systems, algebra, geometry, and trigonometry, primarily in the areas of Mathematics and Science. The origin and inspiration for Indian mathematics is geometry. It originated in India in the construction of the altars meant for Vedic sacrifices.

India has a rich tradition of Mathematics dating back to ancient times. From the development of the numeral system to the concept of zero (0) and pi (π)
Here are the significant contributions of renowned Indian mathematicians, who have shaped mathematics through innovations like the decimal number system, the concept of zero, and advancements in algebra and trigonometry.
Baudhayana was an ancient Indian scholar associated with the Baudhayana Sulba Sutra, one of the earliest Indian texts on geometry. He is known for mathematical ideas related to geometric constructions used in Vedic altar design.
The Baudhayana Sulba Sutra contains an early statement related to what is now known as the Pythagorean theorem. It is more accurate to say that the text presents an early form of this geometric principle rather than claiming that Baudhayana was the original mathematician behind the theorem.
Baudhayana is also associated with early geometric methods, including shape transformations, approximations related to square roots, and geometric constructions.
Main contributions associated with Baudhayana
Aryabhatta was born in 476 CE in Kusumpur (present-day Patna), India. He was the first in the line of outstanding mathematicians from the classical age of Indian Mathematics and Astronomy.
His famous works are the "Aryabhatiya" and the "Arya‐siddhanta".
The Mathematical part of the Aryabhatiya covers arithmetic, algebra, plane trigonometry, and spherical trigonometry. The Arya-siddhanta deals largely with astronomical computation.
He discussed algebraic identities such as
| (a+b)² = a² + b² + 2ab |
He taught the method of solving the following problems:
| 1+2+3+…………+n = n(n+1)/2 1²+2²+3²+……+n² = n(n+1)(2n+1)/6 1³+2³+3³+……+n³ = (n(n+1)/2)² 2 |
Aryabhata was the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His work includes the Aryabhatiya and the Aryasiddhanta.
Numerical values:
He invented a notation system in which digits are denoted with the help of alphabetic numerals.
Notation system:
He invented a notation system consisting of alphanumeric numerals. Digits were denoted by alphabet numerals. Place value: He was familiar with the place value system. He knew numerical symbols and the sign for zero.
Square root and cube root:
His calculations on square roots and cube roots would not have been possible without the knowledge of the place value system and zero. He has given methods of extracting square roots and cube roots along with their explanation.
Algebra:
In Aryabhatiya, he provided elegant results for the summation of a series of squares and cubes.
| 1 + 2 + 3 + 4 + 5 + ......... + n = n(n+1)2 12 + 22 + 32 + 42 + 52 + ......... + n2= n(n+1) (2n+1)6 13 + 23 + 33 + 43 + 53 + ......... + n3= [n(n+1) 2]2 14 + 24 + 34 + 44 + 54 + ......... + n4= n(n+1) (2n+1)(3n2+ 3n - 1)30 |
Interest:
He developed the different methods and a formula for solving questions related to rates, interest and time.
Trigonometry:
Brahmagupta was born in 598 A.D. in Bhinmal city in the state of Rajasthan. He was a mathematician and astronomer who wrote many important works on mathematics and astronomy. His best-known work is the "Brahmasphuta-siddhanta", written in 628 AD in Bhinmal.
| a + ar + ar² + ar³ + …… + arⁿ⁻¹ = a(rⁿ ‐ 1)(r ‐ 1) for r ≠ 1 |
| a, b, c, d = 9 (s‐a) (s‐b) (s‐c) (s‐d), where 2s = a + b + c + d. |
Brahmagupta’s formula should be written clearly as
| Area = [(s-a) (s-b) (s-c) (s - d)] |
Bhaskara II, also known as Bhaskaracharya
He was born in Bijapur, present-day Karnataka. His work made a significant contribution to mathematical and astronomical knowledge in India
Bhaskara II was one of the most important Indian mathematicians and astronomers of the 12th century.
Siddhānta Śiromaṇi ("Crest-Jewel of Astronomical Systems"). This is a seminal 12th-century Sanskrit treatise on mathematics and astronomy. It divided into four parts called
These four sections deal with arithmetic, algebra, and the mathematics of planets and spheres, respectively.
Bhaskaracharya made important contributions to several areas of mathematics. Some of his best contributions to the field of mathematics are the following:
| 61x² + 1 = y². |
| sin(A ± B) = sin A cos B ± cos A sin B. |
Mahāvīra, also known as Mahaviracharya, was the first, 9th-century Jain mathematician who made important contributions to Indian mathematics, especially in algebra and geometry. He is known for stating that the square root of a negative number does not exist within the realm of real numbers.
Mahāvīra was born around 815 CE in the city of Gulbarga, Karnataka, in southern India. Mahāvīra worked under the patronage of the Rashtrakuta king Amoghavarsha and was associated with the mathematical scholarship of his time.
Mahāvīra made significant contributions to mathematics. He also gave rules for the area of certain geometric figures and discussed methods related to the perimeter of an ellipse.
Mahaviracharya mastered a wide range of subjects, from basic to complex topics. Some of his contributions include:
