The Trachtenberg Speed System of Basic Mathematics

best book on speedy math .

Lots of tricks to explore. I come to know the book through my friend. I bought this for my kids. They are enjoying the maths now. I gone through some chapters and got interested. If you are a maths lover, then it is must one. Quality of paper is good. I am using roughly like daily my family reading like conic book but still the book pages are in place. Good quality binding, cover and paper.

It is very best for speed multiplication

Great 👍

Excellent paper quality

The book explains easy way to do numerical calculations and makes arithmetic and numbers interesting. It was a gift to my niece' son.

if you & your kind wants to magic in calculation go for it, step by step approach is truly wonderful

Amazing Book!!! Each and Every topic of the book, like Multiplications, Squares, Square Roots, Rapid Multiplication is explained in such a way that the normal student who is not good in that topic can do wonders if he just practice thoroughly, was searching for this type of books, it is a best book to start the preparation for competitive exams to flourish your basics. Just buy a book and see !!! You will never ever regret ...

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 - anyone can learn it *** Even for someone who is not intimidated by numbers: this is the only book, you'll ever need to become the wizard of every-day-basic maths. Do not for any reason skip any chapter or pages or the entire philosophy WILL elude you ! With pen [indeed: PEN] and paper work your way attentively and meticously through every single exercise - especially the obvious ones ! PLEASE; Stay patient with each of the examples and repeat them over until you're completely mastering its unique technique. About half-way through this book you'll probably find calculators much too slow AND in-accurate [too few digits displayed]; You'll always vision the complete solution in your head long before you've finished punching the calculator's keypad. The division chapters seemed the most difficult ones to me [two entirely independent and very different systems]. One is fool-proof, one is tounge-in-cheek.; you'll need to work through both of them. The latter division system is by far the most difficult part of the entire book - PLEASE brace yourself to put the extra effort into mastering it - and then SELL your CALCULATORs ! Your conception and memory skills as well as self-confidence will be instantly and permanently boosted. Excellent self-study guide for children, too ! It's indeed the very best self-study basic-maths teacher for anyone who shyes away from basic accounting - or just wants a-trick-or-two to improve their calculating-speed.

I have an older edition of this book, and have ordered this edition for a friend. This is an incredible book, you can learn very simple techniques in minutes, that will amaze your friends and family with the speed and ease at which you can do math. You can write the answer down without any calculations as the work is done very simply in your head. This is a book I delve into from time to time, in an effort to really acquaint myself with the techniques. The only prior math’s knowledge you need is the ability to count to 10! Would revolutionise maths if we taught this in schools!

Beaucoup d'exemples pour bien comprendre. Le livre est imprimé « à l'ancienne » (typographie, papier, encre). Le format « poche » permet de l'emporter partout.

Bought for my granddaughter

This is one of my favourite books ever. This is at least my third purchase of this book. My first purchase was when I was in high school, long before the internet was a gleam in the cloud's eye. I have been using their 9's method for checking computations since I was a teenager in my father's business…long before any calculators were available to the public. Yeah, I am old.
