Download pdf file with exercises for section M.4.
Unless you want to do tedious matrix reductions by hand, you will want to use a program for Smith Normal Form. Program in Mathematica. Program in Maple.
Do exercises 1, 3--9, from the pdf file.
(Exercise 3 might be hard, if you don't see the trick. Don't panic if you don't get it.)

Text of first exam.
Mathematica Lesson 1: Getting started.
Mathematica Lesson 2: Mathematica as a scientific calculator.
Mathematica Lesson 3: Mathematica as a symbolic calculator.
Mathematica Lesson 4: Mathematica for calculus and graphing.
Note: sometimes students report difficulty opening Mathematica files with in Windows on university computers. This is not the fault of these files but rather something to do with the way Mathematica and Windows are set up on some of the university computers. The following procedure will work:
1. Click on the www link to the file you want to use and, when the dialogue box pops up and asks what you want to do with the file, chose save to disk. Save it to some convenient location, like the desktop, or your own floppy drive.
2. Start the Mathematica program.
3. Open the desired file from within the Mathematica program; i.e. on the main Mathematica menu bar do File -> Open . A file browser will pop up, and you can choose your file.
