Chapter 1 LOGIC AND PROOF
... As we saw in the last exercise, we can use both ∀ and ∃ in one statement. It is important to clarify the following point about the order in which quantifiers are used. While [∀x, ∀y, p(x, y)] ≡ [∀y, ∀x, p(x, y)] ≡ [∀x, y, p(x, y)], the propositions [∃ y ∀x p(x, y)] and [∀x, ∃ y p(x, y)] are not ...
