y doesn’t sound easy. This is a course in discrete mathematics that addresses questions that begin, . For example, we shall soon know the answer to questions such as, How many ways are there to order 12 ice cream cones if 8 flavors are available? At the end of the course we should be able to answer

For each set ., we let |.| denote the number of elements in . and say that |.| is the . of .. Looking at the top third of the figure, we see a trivial result that is tremendously important. Frequently it is much easier to c

It is, and this common sense is codified as follows, where by a “proposition” we mean any statement that makes sense.
