Not to look a gift horse in the mouth, but I'm always irritated by math books that include practice exercises but no answers in the back of the book to check your work against.



I believe they do this because the real target audience is other professors. The author wants those professors to use their book for their own courses, and a bunch of problems with no answeres saves a lot of time. There seem to be very few books written with the autodidact in mind. Sometimes you can find the solutions manual via eBay or torrent though.
