[R] A Math question

[Maithula Chandrashekhar]

Dear all, I admit this is not anything to do R and even with
Statistics perhaps. Strictly speaking this is a math related question.
However I have some reasonable feeling that experts here would come up
with some elegant suggestion to my question.

Here my question is: What is sum of all Integers? I somewhere heard
that it is Zero as positive and negative integers will just cancel
each other out. However want to know is it correct?

Thanks so much
