Re: Sum of Prime Numbers | 3 Aug 2009

there are 25 prime numbers are there in less than 100.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

and sum of all these numbers is 1060.

Re: Sum of Prime Numbers | 3 Aug 2009

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.

Re: Sum of Prime Numbers | 3 Aug 2009

Re: Sum of Prime Numbers | 3 Aug 2009

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

Re: Sum of Prime Numbers | 3 Aug 2009

Re: Sum of Prime Numbers | 3 Aug 2009

I have replied in the debated threads as well and what mathematics consider it.
