Bana is correct.

"I am good." "I am not good." I'm not sure what you are asking. Both of these are statements. The first is positive, the second, negative. To make them questions: "Am I good?" "Am I not good?" This second sentence is interesting, because it doesn't mean "Am I bad?" It is looking for validation. Putting it in a more casual way: "I'm good, right?" I'm not sure this helps. I hope so. :-)

I am good, aren't I? Or Am I not? I am not good, am I?
