Summary: Disappointing
Comment: I have read the first of Julius' books, "Rapid Math Tricks and Tips", and found it very interesting. Therefore, I eagerly bought this sequel. But as I started reading, I found it very disappointing. The "tricks" are far from as good as the ones in the first book. You can hardly call them tricks at all! I got the feeling that after a successful first book, he had to write a second one. And having told all the good tricks in the first book, he had to come up with something to write in this. And what he came up with is not very exciting.

My recommendation is to buy the first book, and not this.

Summary: Very good
Comment: Great book.Really does get you thinking differently about mathematics.The stuff they teach you in school is just to complicated and drawn out.This is not.A must for those who want to 'cut to the chase'.

Summary: Tricks? yes, but some excellent rapid calculation methods
Comment: While I haven't actually used this book I have used its predecessor and find that the two are very similar in format. I have gone through all 26 of the sample pages and found each "trick" or method is very well designed. Each consists of a concise but clear explanation, two or three fully explained examples followed by two sets of exercises. the first are easy applications; the second harder. All of the methods are valid rapid calculation devices. Unfortunately, most of the multiplication and division methods involve special cases which the average person may not ever see or recognize in typical daily encounters with the need for computation. The addition and subtraction methods are more general. The book will prove most valuable to someone who is already fairly accomplished in computation skills but wishes to brush up on them and, perhaps, to pick up a few rapid calculation methods which can be used very frequently. Otherwise, the book may help one brush up on rusty comp. skills or prove interesting in attempting to discover why the various "tricks" work (the author does not explain the mathematical basis on which the methods rest - he deals in "how-to" not "why?". One final caution - if you have not memorized the basic arithmetic combinations of addition, subtraction, mulltiplication, and division this book is not for you.
