comment Group Theory (Abstract Algebra) question! o(G) vs o(g)??
My guess would be that $o(G)$ is how many elements are in the group and $o(g)$ is the smallest positive integer, $n$, such that $g^n=e$.

comment How do i solve this equation? $2^x+1=x^2$
I way to try to approximate the answer would be to graph $y=2^x+1$ and $y=x^2$ online or on a calculator and estimate the point of intersection.

comment A simple fundamental group
@MarianoSuárez-Alvarez I know what he wrote. But, there is still a very good notion of sphere $1$ and sphere $2$ after they have been identified. And there is still a north pole and south pole after the identification. So, he may have meant take the image of sphere $1$ in the identification minus the (shared) north pole. His reply to my comment seems to indicate that is what he meant. In short, I think he didn't write exactly what he meant.

comment A simple fundamental group
@MarianoSuárez-Alvarez I think he means to delete the north and south poles after he has identified them together. This would result in open sets.

Are you trying to find a countable basis for $\mathbb{R}^2$?

Density is what you use. Can you list out your answer so that we can check to see if it is correct?
