Venn diagram review stuff:

I do pretty much all of the problems from the assignment with the people wearing red and eating hotdogs problems, so that would be a good assignment to have open to look at as you watch my explanations.

Video explanations to watch: (if you watch these on your own computer and they won't play, it probably means that you don't have the latest version of Flash player or perhaps Shockwave installed--I test stuff on Firefox, so you might try that too.  If you watch them in a computer lab you may need to bring in or check out some headphones to listen to the audio)
