This chapter is dedicated to one type of logic, called propositional logic The world logic we will say that the compound propositions p ∨ q and q ∨ p are equivalent propositions We only need to show that ¬p ∨ ¬q is false too, which is the case, since both ¬p The biconditional of p and q: p ↔ q ≜ (p → q) ∧ (q → p)
