This paper presents the Indian sources of some of the most frequently studied mathematical results in schools and colleges around the world. Many of these results are now identified by the name of the mathematician, usually Western or Greek, who is considered to have first discovered it in the Western context. However, documented Indian primary sources do exist to prove that many of these results in algebra, geometry and combinatorics were first discovered by Indian mathematicians at a far earlier date than their Western counterparts. The paper will quote primary sources in Sanskrit, and analyze and interpret the mathematical language used. It will also shed some insight into the processes used by ancient Indian mathematicians to arrive at their results. In particular, it will discuss the Pythagorean Theorem, the quadratic equation, permutations and combinations, and the Fibonacci sequence.
