Query: MUCH Esplainin' to do!

This is the worst math textbook I have ever had the misfortune of coming into contact with. It does no real explaining at all, with the easiest possible examples and no step by step aid. It reminds me of a reclusive, bumbling but idiotic savant genius trying to explain something...in another language! The examples were skeleton problems; worked out in shortcut ways with no reasoning or explaination behind them. There was a little module on the sidebar titled "In words" that would be helpful, but there were too few of them and they were too short. It was very disappointing. Most people use the textbook as supplementary to instructor's notes and lectures, but this book was like the bare bones, with every other piece missing.
