    The correct answer should be "-infinity".
    Because there exist prime numbers < 0.

    Yeah .. don't be surprised. Just google "negative prime numbers". You gets lots of results refer any one :)

    So, sum of all prime numbers = - infinity, because there are infinitely many primes less than 0 ;)

    If my answer will not b accepted, I demand a clarification + a convincing argument to why my answer was rejected.

    I do not consider -ve numbers as prime ( But I open to debate here )

    It's not about you or me ... mathematics won't be modified by either of us.
    And, you didn't consider anything specfic in the question.

    As I mentioned, I need a convincing argument against my views. And, this one was far from that. If you have a very strong reason like why -ve primes don't exist ... post them here / the debate thread :)

    Perhaps, this is the first controversial question posted after PriyaD handed over the responsibility to shabbir :p
