I decided at the age of 38 to start a distance learning program in computer science again. Math was always my problem subject, where I was good at first but later got left behind. To prepare for my studies I'm taking a prep course online, the other day I spent over an hour struggling with the explanation and still didn't understand it. Looked it up in the math bible for 10 minutes and I was able to solve most of the problems.
The complete ebook has almost 4,500 pages. For me, an excellent value for the money!
