The Trachtenberg Speed System of Basic Mathematics by Jakow Trachtenberg, A. Cutler (Translator), R. McShane (Translator), was published by Doubleday and Company, Inc. Garden City, New York in 1960. [1] The book contains specific algebraic explanations for each of the above operations. Most of the information in this article is from the ...
Jakow Trachtenberg (17 June 1888 – 26 October 1951) was a mathematician who developed the mental calculation techniques called the Trachtenberg system. [ 1 ] He was born in Odessa , in the Russian Empire (today Ukraine ).
Mental calculation is said to improve mental capability, increases speed of response, memory power, and concentration power. Many veteran and prolific abacus users in China, Japan, South Korea, and others who use the abacus daily, naturally tend to not use the abacus any more, but perform calculations by visualizing the abacus.
That may be why one study found that people with mild cognitive decline who consumed wild blueberry powder daily for six months demonstrated improved mental processing speed and less cognitive ...

This algorithm uses only three multiplications, rather than four, and five additions or subtractions rather than two. If a multiply is more expensive than three adds or subtracts, as when calculating by hand, then there is a gain in speed. On modern computers a multiply and an add can take about the same time so there may be no speed gain.
