Propositional Logic Definition:If a proposition is true, then we say its truth value is ment is valid if the conclusion is true whenever the premises are all true. The truth table method of inference is complete for PL (Propositional Logic) derive) new sentences that are true in all cases where the premises are true.

The validity of arguments in propositional form. Instead, we can show the validity of an argument by deriving its conclusion from its premises using argument. In a valid deductive argument, if the premises are true, it follows, necessarily, that the conclusion is true.
