wording should say four parts, not three. Also fix formatting.

    3: \textbf{How to deal with multi-part problems}
    4: 
    5: Often, there are several parts in a specific problem. For example, a
    6: problem with four parts may have parts 0, 11, 12, and 13. For a
    7: general spreadsheet, it is often desirable to sum up all of these
    8: parts, while not knowing how many parts there are as the spreadsheet
    9: is written.
   10: 
   11: The spreadsheet has a preprocessor which can expand a symbolic
   12: expression over all symbolic names that match. The general syntax is
   13: \index{EXPANDSUM} \texttt{[\&EXPANDSUM(VARNAME;expression)]}. 
   14: 
   15: \noindent
   16: For example, for the above assessment with four parts,\\
   17: 
   18: \noindent
   19: \texttt{\&EXPANDSUM(}\texttt{\textbf{PART}}\texttt{;parameter\_}\texttt{\textbf{PART}}\texttt{\_weight{*}stores\_}\texttt{\textbf{PART}}\texttt{\_awarded)}\\
   20: 
   21: \noindent
   22: would become\\
   23: 
   24: \noindent
   25: \texttt{parameter\_0\_weight{*}stores\_0\_awarded +}~\\
   26: \texttt{parameter\_11\_weight{*}stores\_11\_awarded +}~\\
   27: \texttt{parameter\_12\_weight{*}stores\_12\_awarded +}~\\
   28: \texttt{parameter\_13\_weight{*}stores\_13\_awarded +}~\\
   29: % bold does not show
   30: % where \textbf{bolded text} is used to highlight what the \texttt{\&EXPANDSUM} function is doing.

   33: \noindent
   34: \textbf{What `tries' means}
   35: 
   36: In multi-part questions, the exported value for ``tries''\index{tries} is 
   37: the average number of tries to get the parts correct. 
   38: The full data for each part is still stored by the system. To assign partial credit based on number of tries, see the example in \textbf{Special Functions} (\ref{Spreadsheet_Functions}).
