If B then A is the same as if X then Y is the same as if A then B. They are saying it’s the same as the OP. Changing the letters around doesn’t change the meaning since the letters are just placeholders.
Now if you said If A then B AND If B then A as one it wouldn’t be the same because A and B would have to keep the same meaning.
No. They are effectively the same statement.
(A <=> B ) = (A=>B AND B=> A)
Also, Not (A XOR B)
Wait. If they are effectively the same statement, wouldn’t that mean they ARE equal?
