A formula of the predicate calculus is in prenex normal form (PNF) if it is written as a string of quantifiers and bound variables, called the prefix, followed by a quantifier-free part, called the matrix. Together with the normal forms in propositional logic (e.g. disjunctive normal form or conjunctive normal form), it provides a canonical normal form useful in automated theorem proving. Every formula in classical logic is equivalent to a formula in prenex normal form. For example, if , , and are quantifier-free formulas with the free variables shown then is in prenex normal form with matrix , while is logically equivalent but not in prenex normal form.

Matthias Baaz: Fast cut elimination in intuitionistic logic
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: In this lecture we provide an elementary procedure to eliminate prenex cuts in LJ without v. (For LK without v the elimination of prenex cuts is nonelementary). As coroll

Pre-Calculus - Solve a linear equation that has no solution
This video shows an example of a linear equation that has no solution. Note how the variables drop away entirely and the statement left over is completely false. That is the clue there is no solution. For more videos please visit http://www.mysecretmathtutor.com
