do it in steps starting with just p and q. p can only be True or False, same with q p<->q is biconditional which means p will be same as q and vice versa Let m = p<->q m -> p means m implies p so if m is true, then p is true Now put it together in a table p q p<->q m->p ----------------------- F F T F F T F F T F F F T T T T
