\section{Useful Environment}
\subsection{Standard Environment}
\begin{frame}{\texttt{itemize} and \texttt{enumerate}}
    This is a demonstration of various environments. The first is \texttt{itemize}:

    \begin{itemize}
        \item Item 1
        \item Item 2
        \item etc.
    \end{itemize}

    Usually I'll use \texttt{enumerate} as well:

    \begin{enumerate}
        \item Item 1
        \item Item 2
        \item etc.
    \end{enumerate}
\end{frame}

\subsection{Customized Environment}

\begin{frame}{Definition, Examples, etc.}
    All the common environments are available, e.g.,
    \begin{itemize}
        \item \emph{Theorem}-related: \texttt{lemma}, \texttt{theorem}, \texttt{corollary}.
        \item \emph{Common} environments: \texttt{definition}, \texttt{example}, \texttt{problem}.
        \item \emph{Others}: \texttt{prev}, \texttt{observe}, \texttt{assumption}, \texttt{remark}, \texttt{intuition}.
    \end{itemize}

    I'll just show you two examples:

    \begin{example}[A demonstration]
        This is an \texttt{example} environment.
    \end{example}

    \begin{prev}
        This is a \texttt{prev} environment.
    \end{prev}
\end{frame}

\begin{frame}{References}
    \printbibliography
