Many years ago, I made up some packets to help students get a refresher before placement tests or before starting a class. If I remember correctly, there *may* be a mistake in there somewhere.... So you can let me know if you think you found it. Each packet has a little lesson, sample problems, and then the answers worked out for those problems. They have been sitting in my computer drive for a long time. I hope they help.
