Does anyone here use LaTeX. Not a Debian question at all, but isn't it possible to define a quantity, say a cash amount \def\yearly {12000} and then have latex calculate from it to enter another figure, say \monthly=\yearly / 12 hoping to get the figure '1000' printed in the document by inserting '\monthly'. Obviously that is not correct markup, but does any wise person know how to achieve that? TIA -- richard
