What is the opposite of ∀?

The opposite of the universal quantifier symbol ∀ ("for all") is the existential quantifier symbol ∃ ("there exists"), with the negation of a "for all" statement (∀x P(x)) becoming "there exists an x such that not P(x)" (∃x ¬P(x)). So, if you see "∀x (x > 0)" (for all x, x is greater than 0), its negation is "∃x (x ≤ 0)" (there exists an x such that x is not greater than 0, i.e., x is less than or equal to 0).
