Indeed, as well as use them to calculate a limit.

You are an idiot: it's the conclusion that I am questioning, not the definitions.

Of course I would not answer yes to those questions: the rule is 2 in for each 1 out, so you cannot end up empty by any logic that is a logic.

WM does not use logic, but you do not appear very much to the point either.
