Question 160240: I don't understand the logic proofs
not k
not l then h
j then k
h then j
therefore l
i understand modus tollens, modus ponens, law of sillogysm and law of contrapositives but not how they apply to a proof as long as the above.
i also don't understand how to do the proofs and reasons, the above has 7 of each
