Description
Proposition to DNF
Derivation
Final term is not finished(~~q || (~r /\ T)) /\ (~~q || (~r /\ T)) /\ ~(~(q /\ ~q) /\ ~(p /\ ~q)) /\ T
⇒ logic.propositional.truezeroand(~~q || (~r /\ T)) /\ (~~q || (~r /\ T)) /\ ~(~(q /\ ~q) /\ ~(p /\ ~q))
⇒ logic.propositional.compland(~~q || (~r /\ T)) /\ (~~q || (~r /\ T)) /\ ~(~F /\ ~(p /\ ~q))
⇒ logic.propositional.notfalse(~~q || (~r /\ T)) /\ (~~q || (~r /\ T)) /\ ~(T /\ ~(p /\ ~q))
⇒ logic.propositional.truezeroand(~~q || (~r /\ T)) /\ (~~q || (~r /\ T)) /\ ~~(p /\ ~q)
⇒ logic.propositional.notnot(~~q || (~r /\ T)) /\ (~~q || (~r /\ T)) /\ p /\ ~q
