Query: This book is really outdated

I've no doubt that the author is/was a mathematical genius. I'm giving two stars instead of 1 because I'm sure it was a great book when it came out...IN THE 80's!!!!!Apologies to the previous reviewer, but this book is out of print for a reason. Discrete Math has developed past the information in this book. The style in which this book is written is ancient and some of the examples are really cryptic. Actually, it doesn't have examples, just theorems and proofs.If you are a teacher evaluating this book for use in the classroom...PLEASE,PLEASE,PLEASE use something more modern. My teacher has decided to use this for a discrete math review. I enjoyed my discrete math class a few years ago when the teacher used a more modern book, but this discrete math review is really boring. Root cause of boredom + head scratching = this book!
