Title: Missing nth root and Prime Factorization
Review: Great books for refreshing your Algebra. I was relying on this rather than my math book as I found this more entertaining and easy to visualize compared to my boring math book. Since I was away from math for awhile though and only had this as a reference, when I wanted to remember what prime factorization was, I was surprised not to find it in here. I had a complete brain fart but eventually remembered the process. However, I was annoyed it was not in the book. Also, it has no help on "nth" roots. So far so good though and I've had it for almost a month now.
Is the review positive or negative?
