--- Introduction ---
In an exercise of dialog, the computer presents a problem,
and it is up to you to ask it questions which would help you selve this problem.
You can solve problem once you have gathered enough information. But you will be
punished if you ask more questions than absolutely necessary!
In this module, you have 3 dialog exercises on matrices.
Please take note that WIMS pages are interactively generated; they are not ordinary
HTML files. They must be used interactively ONLINE. It is useless
for you to gather them through a robot program.
