You are using the wrong kind of outer brackets.
To *evaluate* a filter, use tripled curly braces around the entire filter
expression. Also, you can't "nest" filters, so use a variable to hold the
result of the first calculation, and then reference that variable in the
second calculation.
Finally, *after* computing the desired values, reference the variables to
produce the output.
Thus:
\define Benzkauf2(Datum kmalt kmneu getankt Gesamtpreis)
<$vars v1={{{ [[$kmneu$]subtract[$kmalt$]] }}}>
<$vars v2={{{ [[$getankt$]multiply[100]divide<v1>] }}}>
<$vars v3={{{ [[$Gesamtpreis$]divide[$getankt$]] }}}>
<tr align=right>
<td>$Datum$</td>
<td>$kmalt$</td>
<td>$kmneu$</td>
<td>$getankt$</td>
<td>$Gesamtpreis$</td>
<td><<v1>></td>
<td><<v2>></td>
<td><<v3>></td>
</tr>
</$vars>
</$vars>
</$vars>
</tr>
\end
That should do what you want. Let me know how it goes.
