Hi, I am working on small number integer problems for my thesis and use Maple to do keep track of ugly equations and to do some numerical simulations to see if the results make sense quantitatively.

Now, I use with(RealDomain) and assume to tell Maple some characteristics of my models, but I cannot find a way to tell Maple that most of my variables are integers (number of different agents in small groups). Is this possible?

Related (or not): I have the following:

N_unr:='sum((n_0-2+u)!/(u!*(n_0-2)!),u=0..n_P-2)';

Hi all, probably a simple question: I have a piecewise function that I want to invert. The actual function is the result of a couple of calculations, but here is a very simple testcase: F1:=y=piecewise(x>=0 and x
