This amazing book arrived today. I had the 1960 Edition, and was amazed at the techniques to bring large numbers to conclusion. Prof. Trachhtenberg endured pure hell and still he brought out a manner of math that the world surely needed. My copy arrived in excellent condition, sealed in wrap to keep the cover and pages from being damaged, or worse - water! Thank you having this book -Amazon is the first place I look for almost everything. I highly recommend this book - I am giving it to my college bound grandson........and I know he will enjoy every page!

I get bored with doing math. This has nothing to do with an inability to do math and more to do with the fact that a lot of the work required to do it is tedious. Because of that fact, I've been looking for a easy and fast mental math system to take out the menial work out of doing basic math.
Amazingly, I managed to find a system that fit those requirements: The Trachtenberg Speed System of Basic Mathematics.
First off, let me state that all the 5 star positive reviews are justified. This is, in fact, an amazing mental math system that goes a few steps beyond what's necessary for a mental math book. If it had merely given you a quick way to do addition, multiplication, division, subtraction, and square roots, it would have been a good book, if somewhat indistinguishable from all the other mental math books. There are two things that set it apart from other systems:
1. It gives you a way to check your answer that's quick and works for all operations
2. It's a complete system, not just a set of tricks, thus it anchors it self in your brain.
However, while I do like this book, I have to give a caveat that forces me to knock this book...

I actually had a copy of this book when I was a child, and took great pleasure in learning some of the tips'n'tricks. I was so pleased to purchase this other copy in order to allow my son the same opportunity now. I guess the enjoyment you get out of it would greatly depend on how much you enjoy math games. If you don't, I sure wouldn't buy this! lol But it is very, very instructive and a great purchase for the middle school, high school, or college student. Certainly even math-oriented adults would enjoy learning tricks to make math easier. To me, a good part of the positive in it is just getting kids to *think* about how numbers go together, and how to manipulate them. If you make math fun and interesting, it can only be a plus for their overall education! :)

The below review goes for any edition of the book; be it paperback, hardback, new, old, in any language whatsoever.
I, however, first studied the books' danish paperback edition, published 1950'ish ::
Starting out; you really only need to know how to count one-tru-eleven.
The book sets out by presenting to you an entirely new way to 'think' multiplication: You'll learn to 'read' each individual cipher - stop memorizing of multiplication tables - . Completely mastered in about one lazy afternoon.
Soon, you will be reading and handling numbers as well as ciphers in much the same way you now read books. It's such a joy - both rewarding and addictive - ; provided only your undivided attention and wholeheartedly commitment !
Your memory will work and expand quickly; you'll find yourself dividing, multiplying and adding just for the fun of it - without any support of tools like pen & paper etc., even for billions*billions or division into like a zillion decimals !
In about one month I worked through this book cover-to-cover, read every single page of every chapter, did every single exercise over.
*** This SYSTEM is guaranteed to WORK -...

I was introduced to the Trachtenberg method in the 3rd and 4th grade by my mother, through home study. I was an absolute mess in arithmetic and higher level math. The system gave me the encouragement, confidence and skills to go on - and go on I did, through 8 quarters of calculus for my degree in economics and beyond. This is absolutely the best foundation for any mom and dad that want to help their children with numbers, but are unsure of themselves or their skill. Techniques can be picked up so fast it's unbelievable. Highly recommend; I intend, as an older father with two year old girl twins, to use this book intensively, but not in the immediate future of course. I'd be interested in hearing from other readers on this, and I can be reached at bob_hanks@msn.com.
