Most of the formulas have turned out to be correct, and researchers continue to learn from his work while trying to understand and prove them." India 's mathematical heritage extends far beyond Ramanujan's time. The nation is considered home of the concept of zero. Babylonians had used a space as a placeholder (similar to the role of "0" in the number 101), but this space could not stand alone or at the end of a number. (In our number system , as in theirs, this could be problematic; imagine trying to tell the difference between the numbers 1 and 10 by context alone.)
