(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If I just had the set containing [itex] \pi [/itex] on the real line.

So this is an isolated point. Is this set closed?

3. The attempt at a solution

I think this set is closed because it contains its limit points, because it only has one point.

Am i thinking about this correctly?
