It depends on what area of arithmetic you are talking about It's really useful in some places whereas at times it just involves a lot of learning by rote where normal conventional methods could have their way much more easily. |

According to the book 'The Trachtenberg Speed System of Basic Mathematics', "A thin, studious-looking boy wearing silver-rimmed spectacles was told to multiply 5132437201 times 452736502783. He blitzed through the problem computing the answer—2323641669144374101785—in seventy seconds. The class was one where the Trachtenberg system of mathematics is taught." The book also states that "Educators have found that the Trachtenberg system shortens time for mathematical computations by twenty percent.", although this statement does not seem consistent with the previous example. |
