Well, you can either do a series of expr's to do the math (math just
isn't easy with shell scripts), or use another easier language for this
sort of stuff, like PHP, Perl, or Python (it would seem to make a good
scripting language, it needs to start with a P).
Or you could, for instance, just put this calculation into a separate
executable, then call it from your script if you don't want to convert
your entire script to that language.
