Prenex Normal Form (PNF) is a way of writing a logical formula where all the quantifiers (∀ for universal and ∃ for existential) are moved to the front of the formula, followed by a quantifier-free part.

Steps to convert a formula to PNF:

  1. Eliminate implications and equivalences
  2. Move negations inward
  3. Standardize variables
  4. Move quantifiers to the left
