Hi @KLD,

Thanks for the question! No, those two are not the same as each other. Those are mistaken negations. These two statements would be the same:

X —> ~Y
Y —> ~X

Because you flip the terms and negate them both. But you, in your example, just negated the terms. And those aren’t the same.

Hope this helps! Feel free to ask any other questions that you might have.
