The Trachtenberg Speed System of Basic Mathematics

Գրքի շապիկի երեսը

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

Հեղինակի մասին (1962)

Jakow Trachtenberg was a Jewish mathematician who developed the mental calculation techniques called the Trachtenberg system. He was born in Odessa, the Russian empire in 1988 and worked as an engineer in the Obukhov arms factory. He was a dedicated pacifist and instrumental in organising the Society of Good Samaritans when the First World War broke out. After the Russian revolutions of 1917, Trachtenberg fled to the Weimar Republic where he was later critical of Nazi policies and imprisoned in a concentration camp during World War II. He developed his system of mathematics during his imprisonment. He died in 1953.
