Distributive property in logic
WebIn mathematics, the associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs..

So, to go left to right, assume the antecedent ( P ∧ ( Q ∨ R)) and aim for the consequent ( P ∧ ( Q ∨ R)) → ( ( P ∧ Q) ∨ ( P ∧ R)). Plainly you need to extract the two conjuncts P and ( Q ∨ R) from your assumption. And now obviously the only way forward is to use ...

WebFeb 3, 2024 · Two logical statements are logically equivalent if they always produce the same truth value. Consequently, p ≡ q is same as saying p ⇔ q is a tautology. Beside distributive and De Morgan’s laws, remember these two equivalences as well; they are very helpful when dealing with implications. p ⇒ q ≡ ¯ q ⇒ ¯ p and p ⇒ q ≡ ¯ p ∨ q.
