The Brown–Peterson procedure is a widely known task using mental arithmetic. This procedure, mostly used in cognitive experiments, suggests mental subtraction is useful in testing the effects maintenance rehearsal can have on how long short-term memory lasts.
In September 1813 Colburn was being exhibited in Dublin. Colburn was pitted against the eight-year-old William Rowan Hamilton in a mental arithmetic contest, with Colburn emerging the clear victor. In reaction to his defeat, Hamilton dedicated less time to studying languages and more time to studying mathematics.
A mental calculator or human calculator is a person with a prodigious ability in some area of mental calculation (such as adding, subtracting, multiplying or dividing large numbers). In 2005, a group of researchers led by Michael W. O'Boyle, an American psychologist previously working in Australia and now at Texas Tech University , has used MRI ...

He won the first Mental Calculation World Cup in 2004 and the second Mental Calculation World Cup in 2006. [1] [2] [3] In 1999 he was recognised by the Mind Sports Organisation as the first Grandmaster of Mental Calculation. Fountain was inspired to take up mental calculation as a hobby at the age of 11 after seeing Wim Klein performing on ...
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.
