the trachtenberg system of speed mathematics

As these youngsters became proficient in handling numbers they began to spurt ahead in all their studies. Equally important were the byproducts the pupils garnered while learning the new system. The feeling of accomplishment soon made them lose their unhappy traits. The childrens response to the new easy way of doing arithmetic was immediate. These were children used to failure shy and withdrawn or the other extreme boastful and unmanageable. To demonstrate his method Trachtenberg chose children who were doing poorly in their school work. Instead he just wrote down the answer without any of the intermediate steps. He never set up the basic and familiar line by line chart multiplying and adding each row of numbers. In one demonstration a ten year old kid when asked to multiply 5132437201 times 452736502785 simply wrote on the blackboard the answer 2323641669144374104785 in seventy seconds.

Children who had repeatedly failed in arithmetic until their parents sent them to learn this method were able to perform amazing calculations within seconds.

The Trachtenberg Speed System of Basic Mathematics is a revolutionary system for calculating and teaching basic math. Same info as in the book but easier to understand (for me) and talks you through every step.Ishi Press The Trachtenberg Speed System of Basic Mathematics by Jakow Trachtenberg Translated by Ann Cutler Introduction by Sam Sloan I study once a week for a couple of hours and have been for about 2 months but also practice when out shopping like I said.Ī good free site I found helpful to use alongside the book is Good memory recall is obviously an important skill to have and will need improving if you're going to stand a chance doing sums of that length. The claims of a boy doing very large multiplications doesn't sound like it's impossible but would take a good few months of practice. Give me a pen and paper and I can now do the same sums often in under 10 seconds. 3-4 digit multiplications (ie: 2873 x 231) in my head now generally take me around 15-30 seconds to work out (depending on the numbers) with almost 100% accuracy, about a month ago I would be able to do them in about 30-40 seconds ~80% correct. Your question is hard to answer but I will say that where as before I'd simply give up on trying to do large multiplication in my head (as it would be impossible), now I actually am able to do the large multiplications and check them with good accuracy in my head. Studying and practicing the Trachtenberg System has helped me DRASTICALLY improve my day to day mental arithmetic, especially noticeable when out shopping and working out the cost savings in buying bulk and cost comparisons per kilo.
