What were the contributions of the Indians towards mathematics?
Definitively, the decimal-place-and-zero number system was mainly the input of Indian mathematics, but a lot more would be speculation. Ramanujan made many discoveries, but his main inputs were in modular functional equations; much more of his work consists of number-theory niceties and merely reworking through discoveries already known. Objective accounts of more data are difficult to find [I make no pretense that I’m giving SR fair credit]; check http://en.wikipedia.org/wiki/Indian_Math… I didn’t put it as a source because it doesn’t describe what I’m saying.
Nothing but “Vedic Mathematics”. No Indian mathematician could ever simplify Vedic Mathematics sincce inception of it in ancient India! A great Indian contribution to Mathematics is they carried VedicMathematics forward “as it was first concieved by ancient Indians” though related basics are missing! Concept of zero is not linked with Vedic Mathematics, which is a great failure of Indian mathematicians!
