  \frametitle{\typ{Summary}}
  \label{sec-8}
  In this tutorial, we have,
  \begin{itemize}
    \item Gained an understanding of the basic structure of a LaTeX document, its various document classes and loading packages that add new features to 
    \item   the LaTeX system.
    \item Created a LaTeX document with a title and an abstract.
    \item Created both numbered and non-numbered sections and subsections in a LaTeX document.
    \item Created an appendix in a LaTeX document.
    \item Created a table of content in a LaTeX document.
  \end{itemize}

  \frametitle{\typ{Self assessment questions}}
  \label{sec-9}
  {\footnotesize 
  \begin{enumerate}
    \item  Is the LaTeX code given below a valid input file (File compiles successfully and produces the intended result, that is to produce a book with two chapters and an appendix.
  {\tiny 
    \begin{center}
      \begin{verbatim}

          Main
          \chapter{So We say goodbye}
          Thank you for reading dear reader
          \appendix
            \section{First Appendix}
        \end{document}
      \end{verbatim}
    \end{center}
    }
    \item subsection command can be placed at any arbitrary level. If they get numbered by default using the appropriate setcounter command and secnumdepth parameter, do they automatically appear in the table of content ?? 
  \end{enumerate}
  }
\end{frame}

\begin{frame}[fragile]
\frametitle{\typ{Solutions}}
\label{sec-10}
\begin{enumerate}
\item Although the given file looks syntactically valid, the output file is not what we expected. This is mainly because we are trying to use the section command to create sections in the appendix, for a document whose type is given as a book.
\vspace{15pt}
\item No, the \textbackslash tableofcontents  command normally shows only numbered section headings, and only down to the level defined by the tocdepth counter.
\end{enumerate}
