Not entirely sure to understand what you really need and why you can't just perform the arithmetic operations with Perl. If it boils down to evaluating arithmetic expression, maybe you could use eval, but there might be some security problems, so you have to check that the expression to be evaluated is safe prior to doing it.

Another possible option that comes to my mind is to shell out to the bc Unix or Linux utility. bc can be used in non-interactive mode in various ways, including piping (echo "42/7" | bc), shell redirections, and Un*x heredocs.
