IMPLIES MEANS IF BOTH P & Q R TRUE OR BOTH FALSE THEN P <-> Q IS TRUE OR ELSE IF EITHER IS FALSE
P <->Q IS FALSE

Implies s true in only one direction.......

Statement A => Statement B

means if A is true B is also true, but if B is true, A may not be true......

Double implication, "the if and only if" clause, is true in both the directions

Statement A <=> Statement B

means if A is true B is also true, and if B is true, A is true...
