Rapid mental computation system as a tool for algorithmic thinking of elementary school students development. European Researcher 25(7): 1105–1110, 2012 [1] . 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 ...
Note that if n 2 is the closest perfect square to the desired square x and d = x - n 2 is their difference, it is more convenient to express this approximation in the form of mixed fraction as . Thus, in the previous example, the square root of 15 is 4 − 1 8 . {\displaystyle 4{\tfrac {-1}{8}}.}
The Mental Calculation World Cup 2016 was held from 23 to 25 September 2016, in Bielefeld Germany. 31 mental calculators from 16 countries participated. The World Cup involved the following 5 main contests: Adding ten 10-digit numbers, 7 minutes Winner: Yuki Kimura (Japan) Multiplying two 8-digit numbers, 10 minutes Winner: Lee Jeonghee (South ...
The minuend is 704, the subtrahend is 512. The minuend digits are m 3 = 7, m 2 = 0 and m 1 = 4. The subtrahend digits are s 3 = 5, s 2 = 1 and s 1 = 2. Beginning at the one's place, 4 is not less than 2 so the difference 2 is written down in the result's one's place.

In his article, Miller discussed a coincidence between the limits of one-dimensional absolute judgment and the limits of short-term memory. In a one-dimensional absolute-judgment task, a person is presented with a number of stimuli that vary on one dimension (e.g., 10 different tones varying only in pitch) and responds to each stimulus with a corresponding response (learned before).
