This equation is just a shortcut, so I can't see how can it be ill-typed. It means something like: if you add one element to an infinite list, will it be longer?
What does your intuition say about this?
Well, Archimedes thought: "..in the palimpsest we found Archimedes doing just that. He compared two infinitely large sets and stated that they have an equal number of members. No other extant source for Greek mathematics has that." http://news-service.stanford.edu/news/2002/november6/archimedes-116.html -- Chris
