Math 18

Below are a few videos that I have made that correspond to some precalculus topics. There are also videos made by other instructors that correspond to topics on our Math 18 worksheets. More of these outside videos can be found at the website: mathispower4u.com. Another great website for math videos is patrickjmt.com.
