Bu showing, as you and other have done here, an explicit bijection from N to Q (or Q+).

Watch the pea, see the shells move. Is under any? Is not under all? Is it not under every shell?

A fact of set theory and of WMaths.

What is missing (again and again) is a formula that's true is set theory and false in WMaths. Same maths, deceptive words.
