The laws of logical equivalence include the commutative law, associative law, distributive law, identity law, negation law, and double negation law. WebPropositional Logic In this chapter, we introduce propositional logic, an algebra whose original purpose, dating back to Aristotle, was to model reasoning. In more recent times, this algebra, like many algebras, has proved useful as a design tool. For example, Chapter 13 shows how propositional logic can be used in computer circuit design.
