Help WIth Very Basic Conditional Rules

Postby youknowryan » Sun Sep 19, 2010 10:16 pm

I'm writing an outline and want to make sure I have these basic conditional rules straight. Are these all correct?

Conditional Rules:
Rule: A → B, Contrapositive: ~B → ~A
Mistaken Reversal: B → A
Mistaken Negation: ~A → ~B

Rule: ~B → ~A, Contrapositive: A → B
Mistaken Reversal: ~A → ~B
Mistaken Negation: B → A

Rule: ~A → B, Contrapositive: ~B → A
Mistaken Reversal: B → ~A
Mistaken Negation: A → ~B

Rule: A → ~B, Contrapositive: B → ~A
Mistaken Reversal: ~B → A
Mistaken Negation: ~A → B
