Hi all,

I'm struggling with the translation of "cannot."

In an In/Out game if A & B "cannot" be together, then:

  • is A (--) not B and B (--) not A (or rather, is a biconditional relationship necessarily created)? because they are always apart/never together?
  • In a Grouping game, if A & B "cannot" be together, then:

  • is a negate necessary the only result? - is A ---> not B and B --> A?

      Do you have the test and game number?

      Hi @akikookmt881,

      • In/Out Game

      If A and B cannot be together and A and B have to be in the In group or the Out group, then you have to represent it as A (---) /B.

      • Grouping Game

      There are more than two groups with items that are not repeatable, and A and B cannot be together, you should represent it as A ---> /B because this means that if A is in one group, B cannot be in that group. There is no particular Out group. We look at each group as "In group", and we see that if A is in a group, B has to be in other groups.

      This discussion might clear things up:
