WebEvery statement in propositional logic consists of propositional variables combined via propositional connectives. Each variable represents some proposition, such as “You liked it” or “You should have put a ring on it.” Connectives encode how propositions are related, such as “If you liked it, then you should have put a ring on it.” WebA direct proof of a conditional statement p → q assumes p is true, then takes steps to show that if p is true, then q must also be true. Definition 1 The integer n is even if there exists an integer k such that n = 2 k , and n is odd if there exists an integer k such that n = 2 k + 1.
