Propositional calculus | Rules of inference
Negation introduction is a rule of inference, or transformation rule, in the field of propositional calculus. Negation introduction states that if a given antecedent implies both the consequent and its complement, then the antecedent is a contradiction. (Wikipedia).
Determining the negation of a hypothesis and conclusion from a statement
👉 Learn how to find the negation of a statement. The negation of a statement is the opposite of the statement. It is the 'not' of a statement. If a statement is represented by p, then the negation is represented by ~p. For example, The statement "It is raining" has a negation of "It is not

Natural Deductive Logic: RULES #2 (vI, vE, DN, RAA) - Logic
In this video on #Logic, we learn four more rules for natural deductive proofs. We learn disjunction introduction, disjunction elimination, double negation, and reductio ad absurdum (negation introductions, or proof by contradiction). Then we do two example proofs. #PropositionalLogic #Lo
