While there is some level of whitewashing going on, there's a lot of hyperbole of what was discovered during the Vedic period.

Not sure why there's even a need to amplify/attenuate the contributions. There are Indian mathematicians today who are making significant contributions. Probably more productive to focus on mathematical developments in general rather than assigning credit to the past. Assigning credit to a culture is problematic. What about the culture enabled the mathematical development?

Perhaps one day we'll move past assigning credit and towards purely developing ideas in the spirit of the Upanishads written in anonymity.
