The teacher called on a nine-year-old boy who marched firmly to the blackboard upon which was a list of numbers a yard long. Standing tiptoe to reach the top, he arrived at the total with what seemed the speed of light.
Trachtenberg method for beginners
A small girl with beribboned braids was asked to find the solution of 735352314 times 11. She came up with the correct answer-8088875454-in less time than you can say the multiplication table. A thin, studious-looking boy wearing silver-rimmed spectacles was told to multiply 5132437201 times 452736502785.
He blitzed through the problem, computing the answer-2323641669144374104785-in seventy seconds.
Trachtenberg calculatorThe class was one where the Trachtenberg system of mathematics is taught. What made the exhibition of mathematical wizardry more amazing was that these were children who had repeatedly failed in arithmetic until, in desperation, their parents sent them to learn this method.
