Disclaimer
I provide these detailed keys so students can see how to do each problem and correct their homework before the test. I try to make sure that my work is accurate. However, there may occasionally be a problem that I do wrong. If you notice this, please email me as soon as possible. Remember, if you're the first to notice, you'll get extra credit!

Some of these keys are provided by Ms. Duncan.


 * Can't get the keys to open?** Make sure you have [|Adobe Reader] installed on your computer. It is free, respected software that will be useful for more than just this class.
