In logic, a disjunction is a compound sentence formed by using the word or to join two simple sentences. Makes it easier to do logical manipulations, makes sure you know the real meaning without any of the missing/hidden details of natural languages. CHAPTER 14 Predicate Logic We now turn our attention to a generalization of propositional logic, called “predi-cate,” or “ﬁrst-order,” logic. Conversely, a deductive system is called sound if all theorems are true. The same logical manipulations can be done with predicates. For educational purposes only.

Topics include functions, relations, propositional and predicate logic Use the following to answer questions 1-5: laws of logic. For propositional logic and natural deduction, this means that all tautologies must have natural deduction proofs. An argument is a series of reasons supporting a conclusion. Example systems in which the inference engine reasons from facts to conclusions. The schemes of traditional predicate calculus with equality are examples which are not simple metalogic, because they use wff metavariables with arguments and have "free for" and "not free in" side conditions. calculator.
