I put together a list of practice problems for the final exam, which you should use as a guide for the types of problems to expect. If you can handle each type of problem, you should be in great shape for the final exam!
Update: There was a typo in Practice Problem 1. The last word of the sentence should have been “even,” not “odd.” That has been corrected now. Sorry!
Update #2: Another typo was found, this time in Problem 4. The assumption should have been that $A\times C = B\times C$. That has now also been corrected. Hopefully this is the last of the typos!
