Synopsis :

Do high-speed, complicated arithmetic in your head using the Trachtenberg Speed System.

� propos de l?auteur: 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.

Paperback. Etat : Very Good. Do high-speed, complicated arithmetic in your head using the Trachtenberg Speed System. Ever find yourself struggling to check a bill or a payslip?

Using a series of simplified keys it allows anyone to master calculations, giving greater speed, ease in handling numbers and increased accuracy. Jakow 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. It is the perfect way to gain confidence with numbers. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.
