Sure, but if you can you must. And in this case you can.
IMO you are still confusing contracts with behavior. They are different
for exactly the reasons you mentioned, it is impossible to describe
everything through contracts. The object state is the part of what
*cannot* be fully contracted. It is the program behavior when you decide
if you call "+" or "-" with given numeric objects. The contract is that
you can call either.
