Important Note: These problems are taken from Rosen's
``Discrete Mathematics and its Applications'', 5th Edition.
In problems where the
reasoning isn't totally
obvious, EXPLAIN your reasoning. This is an important part of
the thinking process (and also gives you a chance for partial credit).
Note that there are solutions to some of the problems (but not any of
the ones assigned for homework) at the end of the book. You may want
to check them out to get ideas for the assigned problems.
