Predicate Logic, Valuations, Part 2 (Quantified Wffs):

Описание: This video aims to give you the very basics in determining the truth values of predicate logic wffs where the main operator is a quantifier (quantified wffs). It glosses over some of the problems and complexity of doing this in an effort to give you a rough and ready way to assign truth values to quantified wffs.
