More Rapid Math: Tricks and Tips: 30 Days to Number Mastery

I use this with my kids all the time. They are all math lovers and they enjoy figuring out how the tricks "work". However, the biggest hit I've had in doing these in public is with people, adults and children, that somehow have qualified themselves as "non-math people". When I show them the tricks and immediately ask them to do them themselves they light up - they get all excited. This is a must have book for all math teachers and parents. This is a way to keep math fun and relevant. Relevant in the sense that most of the computations are things we need to do daily.

This is a great book, I keep buying it for those I care about. It shows math tricks that are so interesting to learn. It fires the mind of every one that reads it. The real TRICK is getting someone to actually read it, reason I buy and give as gift. Some people need years before the TRICK of reading hits them and next meeting is with my new friend that is math person for the rest of thier life.

Tricks and Tips for understanding shortcuts to maths problems. Yes it is called Mathematics. So now we have covered the English lesson, buy it to get round mathssssss problems.

The book is okay, maybe just proving I'm not a mathematician

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.

I've played with this book and its predecessor (Rapid Math Tips and Tricks) for years and they are favorites. I also recommend Benjamin and Shermer; and Jerry Lucas. Lucas's book started me on this kick. With practice- and you must practice- problems that would have taken me 5 minutes to do mentally now seem ridiculously easy and take 10 seconds or less.

My husband really likes the tip and tricks. They make adding and subtracting quick and easy.

I use a calculator all day so, I like using this book to train my mind to think and think quickly.
