For one of the questions in my Discrete Mathematics course, I have to find what property of a formula makes its dual formula also its negative. With a dual formula, the logical operators of "^" and "v" are reversed, the former meaning "and" and the latter meaning "or". With its negative, all the letters in the equation are simply given a negative sign in front of them, turning positives into negatives and vice versa.

I hope someone can help!
