So here’s my problem.

I’m trying to do this myself through my many notes and books and so far I can understand the idea of “either or but not both” as mutually exclusive, you have one or the other, and I understand that the above in quotes actually means two rules with two contra positives. What I don’t get is how to phrase them right, specifically, in PT 9 game 2.

“Either J or K must be selected, But J and K cannot both be selected”

Doesn’t either or mean: j —> ~k K —> ~j

And “not both” mean: ~j —>k ~k—>j

Cause I’m watching this video on YouTube and it has:

Either or ~j—>k ~k—>j

Not both J—>~k K—>~j

I’m asking because I’m trying really hard to understand this so when a rules comes up without the closing loop”but not both” I can spot it for what it is and write it correctly or I will trash that game and loose out on easy points, so please help cause I’m about to cry
