No, fuck off. The single thing that would be cringier than that would be adding in Yukarifag.

There isn't. The interest in set theory on this board is next to zero.

Nigga did you really make this thread for this?

I don't think it converges.
We set [math]f(n)= \Sigma _{p ~ prime, ~ p<n}\frac{p}{n}[/math].
Then, for a prime p, [math]f(p+1)-f(p)[/math] should go to one when [math]p[/math] goes to infinity.

Yes.
Negative numbers aren't natural, so in some definitions (i.e. wikipedia's) they aren't natural trivially.

A prime [math]p[/math] is a natural number whose natural divisors are [math]1[/math] and [math]p[/math].
