Jakob Trachtenberg believed that everyone is born with phenomenal abilities to calculate, he devised a set of rules that allows every child to make multiplication, division, addition, subtraction and square-root calculations with unerring accuracy and at remarkable speed.
The Trachtenberg system has been described as the 'shorthand of mathematics' and only requires the ability to count from one to eleven. Using a series of simplified keys, it allows anyone to master numbers and calculations.
Jacob Trachtenberg was born in 1888 and invented his system of mental mathematics while imprisoned in a Nazi concentration camp during WW2 and founded the Mathematical Institute in Zurich in 1950 to teach his new method of understanding mathematics.
"Teachers should read this book... which could well revolutionise the teaching of mathematics in the future." -Teachers' World
"I tried an extract on a well-known woman journalist, very capable in her own field, but barely able to count. The result was magical." -Sunday Telegraph
