Query: Is this book talking about math? Did I miss something?

I am a college student and had the unfortunete experience to have to use this utterly useless textbook for two different courses--a finite math and a calculus course. The text is very technical and wordy, with terrible examples not explaining steps but rather using the authors 'ego-boosting' terms such as 'obvioulsy', 'of course' and 'simply' -- wrongly assuming that drawn out text taught the student something. Do not buy this book if you are looking to learn calc--there has got to be something better.
