Query: Value for money? Yes, if you equate number of words per dollar.

I grabbed this in order to brush up on some theory prior to grad study.Haven't finished it, but so far...Way too wordy, and the maths in the examples often skips steps, making the examples less helpful than they might otherwise be. The occasional maths error lends itself to the appearance that the examples were put together by someone in a hurry.There are better textbooks out there. This is great value for money on kindle, but have to say, glad I didn't buy the print version.
