\section{Purpose}

\begin{itemize}
    \item A user can simplify / reduce a mathematical expression.
    \item Program can verify the user's reduction step.
    \item A user should be able to ask for zero, one or more hints (with a
    maximum of one hint per reduction step).
    \item Program can generate exercises using predefined templates.
\end{itemize}

\section{Components}

\subsection{Input parsing and canonical form}

\begin{itemize}
    \item Parse expressions and interpret functions (\texttt{integrate()},
    \texttt{expand()}, \texttt{diff()}, etc.). This will include building a
    parser generator using \emph{bison} and \emph{flex}.
    \item Canonicalize an expression: $4 + x^2 + x \rightarrow x^2 + x + 4$.
\end{itemize}

\subsection{Validation and tutoring}

\begin{itemize}
    \item Validate expressions with the expression of given exercise.
    \item If requested, select the best hint (based on the chosen strategy).
    \item Generate exercise using predefined templates.
\end{itemize}

\subsubsection{Modules}

\begin{itemize}
    \item \emph{TODO}
\end{itemize}

\subsection{Graphical user interface}

\begin{itemize}
    \item Mathematical notation viewer:
    \begin{itemize}
        \item Rewrite shell expressions to \LaTeX.
        \item \LaTeX $ $ to HTML/CSS/JS using \emph{MathJax}.
    \end{itemize}
    \item View hints (if requested by the user) in the notation viewer.
    \item Evaluate the GUI with some early adopters (few pupils and a teacher).
\end{itemize}

\subsection{Screencast, tutorial and final report}

\begin{itemize}
    \item Create a screencast to demonstrate the project.
    \item Write a few short-length tutorials (how to use the system).
    \item Write the final report (e.g. evaluation of the project).
\end{itemize}
