Hello!
I understand that when doing LG, to help chain up the rules, sometimes you need to contrapose conjunctions and disjunctions ("and" turns into "or," and "or" turns into "and"). However, I'm struggling to remember how the flipping and negating goes. Does anyone have any tips on this?
E.g.
Original: G and S --> /I
Contrapositive: I --> /G or /S
Am I doing this correctly?
OR is it:
/G or /S --> I
(Do we flip conjunctions/disjunctions when contraposing, or just negate?)
