... never have been found by a brute-force computer search! The symbols ∀ ( for all”) and ∃ (“there exists”) are called quantifiers. A quantifier is always followed by a variable (and perhaps an indication ... indication of what values that variable can take on) and then a predicate that typically involves that variable. The predicate may itself involve more quantifiers. Here are a couple examples of statements ... prove that some statement holds for all natural values of a variable.
