Lecture.7
Thing are starting to get more complicated but equally interesting. This might be a little further out there than we've covered, but after Prof's explanation of "U" - union and intersection (i'll find a site to get symbols soon enough), I started to think "are we going to deal with multiple sets like; P(x) => Q(x) => R(x)..."
That stuffs gonna get tough if we have to start negating, etc., formulas of that length and some, so i'm planning on practicing these things with visuals like Venn Diagrams. Hopefully it helps.
