Dear All

According to MS Chimbo there can never be more than one main connective in a sentence. I read through pages 121 - 125 again. Makes more sense now.

Thanks fkmare .One more question ,for the 4 sentences , at times the negated normal form is already in CNF/DNF . Then you just convert into CNF/DNF . Am I right ?

Hi

That is what I did. I looked at the definitions for when is a sentence in CNF or DNF form and it made more sense.
