# Calculations ignored on a fresh MiKTeX install

On a fresh MiKTeX 2.9 install, previously working piece of code

\begin{tabular}{>{}p{9em}p{\linewidth-12em}}


is not working anymore — -12em is being outputted in table row fields instead of being calculated. What have I missed?

For that to work the calc package is necessary. It may have happened that a package used to load it and doesn't now in a more recent version. –  egreg Feb 15 '12 at 10:27
expl3 has removed the loading of calc recently. –  Ulrike Fischer Feb 15 '12 at 10:29
@Ulrike Thank you, that's it. –  ipavlic Feb 15 '12 at 10:32
