I am writing some math homework in LaTex and I would like to format somehow like this:
10.2) Question Statement
Meaning, I would like the question statement stand out, either in a colored box like above, or in some other way. Is this possible? Thank you.
EDIT: Here is an example of how I would like to to look like:
10.2) Let $R$ be an integral domain. Show that if $R[x]$ is a principal ideal domain, then $R$ is a field.
Proof: The map $\varphi : R[x] \to R$ defined by $\varphi: p(x) \mapsto p(0)$ is a surjective homomorphism with kerned $(x)$. By the first isomorphism theorem, we have $R[x]/(x) \cong R$. Furthermore, $(x)$ is a maximal ideal, is a prime ideal, and because $R[x]$ is a principal ideal domain, $(x)$ is maximal. Therefore $R[x]/(x)$ is a field, so $R$ is a field as well.
