Prenex Normal Form. According to step 1, we must eliminate !, which yields 8x(:(9yr(x;y) ^8y:s(x;y)) _:(9yr(x;y) ^p)) we move all negations inwards, which yields: Web gödel defines the degree of a formula in prenex normal form beginning with universal quantifiers, to be the number of alternating blocks of quantifiers.
