comment if $X\subseteq Y$, then $\bar{X} \subseteq \bar{Y}$
@MAS I believe Pedro is taking the definition of $\overline{X}$ to be "the smallest closed set containing $X$".

comment Convergence of the Power Series of $\log(1+\sin x)$
@square_one It could be that the author of the question intended you to "formally" expand the power series, which is a fancy term for "write the terms of the power series and ignore issues of convergence".

comment Is there a great mathematical example for a 12-year-old?
@Shahab I meant that the interested individual could move to larger classic Ramsey numbers, multicolor versions, infinite versions, non-clique versions, and so on. These all fall under the umbrella of "Ramsey Theory", but none of it was work of Frank P. Ramsey.

comment Need example for a topological space that isn't connected, but is compact
What are all these spaces you list in your question?
