Query: terrible book

I keep thinking as I'm forced to use this book for a college course, that Discrete Math would not be so confusing to me if not for this textbook. With a good textbook, I believe the concepts would not be very difficult, but this book makes them so. True, they have many examples - very few of which cover the complex things you are then asked to do in the Exercises. If I could give it negative stars, I would, since it doesn't teach us but confuses us.
