\textbf{How to deal with multi-part problems}
Often, there are several parts in a specific problem. For example, a
-problem with three parts would have parts 0, 11, 12, and 13. For a
-general spreadsheet, it is not often desirable to sum up all of these
+problem with four parts may have parts 0, 11, 12, and 13. For a
+general spreadsheet, it is often desirable to sum up all of these
parts, while not knowing how many parts there are as the spreadsheet
is written.
The spreadsheet has a preprocessor which can expand a symbolic
-expression over all symbolic names that fit. The general syntax is
+expression over all symbolic names that match. The general syntax is
\index{EXPANDSUM} \texttt{[\&EXPANDSUM(VARNAME;expression)]}.
