Thanks - By: Phillip Martin, 22 Feb 2006 
The contents of this book should be printed on gold leaf!
A person found time to record this work whilst facing death.
A work that removes the shroud of mystery that covers a branch of mathematics that holds painful memories for many people.
Mental Maths.
Mathematicians manipulate numbers with ease; general members of the public or school kids don't.
This book shows worked examples of how to do various calculations easier & quicker than 'conventional' means.
Example.
23 x 11
2 is the 'first digit'
3 is the 'last digit'
2 + 3 is the 'middle digit'
So 23 x 11 = 253
Many more examples & information are presented, so that with practice the 'sums' can be done in your head.
It's maths without the tears.
Incredible - By: , 22 Nov 2005 I have an older edition of this book, & 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 & family with the speed & 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 reallly 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!
An Excellent book for all people in all walks of life - By: , 01 Oct 2001 This book shows you a wonderful step by step method for improving mental calculations that you use everyday without realising. By learning the methods described your confidence in using mathematics will sky rocket. I cannot recommend this book highly enough.
A great resource. - By: , 08 Jan 2001 I originallly read this book when I was 13 & I have remembered it ever since. When I started vocational teaching of disadvantaged adults I remembered it & bought a copy for my students. I was impressed with what my students achieved & the faculty was astounded.
Definately worth a read! - By: , 01 Sep 2000 A good book for those who want better mental arithmetic skills. Whilst a large number of the basic techniques applied were discovered by mathematicians well before Trachtenburg was born (Euler & Cauchy come to mind), this is almost certainly the first time that the thinking was brought to bear on simple arithmetic in such a systematic fashion.
