Aaryan Shukla is an Indian mental calculator and board member of the Global Mental Calculators Association. [1]
Shukla won the 2022 Mental Calculation World Cup at the age of 12 years old, [2] [3] setting event records in multiplication and square roots in the process. Additionally, during the record attempts portion of the event, he broke the organizer's record for division [4] and multiplied two 20-digit numbers together in 1 minute and 45 seconds. [5]
Shukla returned to the Mental Calculation World Cup in 2024, winning the event for a second consecutive time, while winning all five categories and scoring more points per category than any prior competitor. [6] Additionally, he set the following records during the event:
Shukla also became the youngest winner at the Mind Sport Olympiad Mental Calculation World Championship in 2021, [8] before finishing as runner-up twice. [9] [10] He also finished as runner-up in Season 1 of Calculation League. [11]
In 2023 and 2024, Shukla gave televised Flash Anzan performances in Russia and Italy, the latter earning him a Guinness World Record in addition. [12] [13] [14] [15] [16]
A slide rule is a hand-operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry. It is one of the simplest analog computers.
Napier's bones is a manually operated calculating device created by John Napier of Merchiston, Scotland for the calculation of products and quotients of numbers. The method was based on lattice multiplication, and also called rabdology, a word invented by Napier. Napier published his version in 1617. It was printed in Edinburgh and dedicated to his patron Alexander Seton.
A scientific calculator is an electronic calculator, either desktop or handheld, designed to perform calculations using basic and advanced mathematical operations and functions. They have completely replaced slide rules as well as books of mathematical tables and are used in both educational and professional settings.
A mental calculator or human calculator is a person with a prodigious ability in some area of mental calculation.
Mental calculation consists of arithmetical calculations using only the human brain, with no help from any supplies or devices such as a calculator. People may use mental calculation when computing tools are not available, when it is faster than other means of calculation, or even in a competitive context. Mental calculation often involves the use of specific techniques devised for specific types of problems. People with unusually high ability to perform mental calculations are called mental calculators or lightning calculators.
Shakuntala Devi was an Indian mental calculator, astrologer, and writer, popularly known as the "Human Computer". Her talent earned her a place in the 1982 edition of The Guinness Book of World Records. However, the certificate for the record was given posthumously on 30 July 2020, despite Devi achieving her world record on 18 June 1980 at Imperial College, London. Devi was a precocious child, and she demonstrated her arithmetic abilities at the University of Mysore without any formal education.
Windows Calculator is a software calculator developed by Microsoft and included in Windows. In its Windows 10 incarnation it has four modes: standard, scientific, programmer, and a graphing mode. The standard mode includes a number pad and buttons for performing arithmetic operations. The scientific mode takes this a step further and adds exponents and trigonometric function, and programmer mode allows the user to perform operations related to computer programming. In 2020, a graphing mode was added to the Calculator, allowing users to graph equations on a coordinate plane.
The soroban is an abacus developed in Japan. It is derived from the ancient Chinese suanpan, imported to Japan in the 14th century. Like the suanpan, the soroban is still used today, despite the proliferation of practical and affordable pocket electronic calculators.
The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other features. The SR-50 was introduced in 1974 and sold for US$170. It competed with the Hewlett-Packard HP-35.
The abacus system of mental calculation is a system where users mentally visualize an abacus to carry out arithmetical calculations. No physical abacus is used; only the answers are written down. Calculations can be made at great speed in this way. For example, in the Flash Anzan event at the All Japan Soroban Championship, champion Takeo Sasano was able to add fifteen three-digit numbers in just 1.7 seconds.
The Mental Calculation World Cup is an international competition for mental calculators, held every two years in Germany.
Alexis Lemaire is a mental calculation world record holder. He holds a Ph.D. in Computer Science related to artificial intelligence from the University of Reims. He is also the owner of world records for mentally calculating the 13th root of 100-digit numbers and 200-digit numbers.
Jan van Koningsveld is a mental calculator.
Gert Mittring is a German mental calculator. He was inspired by the late Wim Klein. He has competed in the MSO mental calculation event every year since 2004, failing to win the gold medal outright on only four occasions. He has held numerous world records for mental calculation, such as calculating the 89247th root of a 1000000 digit number. He has doctorates in statistics and mathematics education, and is a member of the Intelligence Research Committee of Intertel. Mittring is said to have been poor in math during his school years. He has written several books on mental calculation.
Alberto Coto García is a Spanish mental calculator. He was the world champion in mental calculation from 2008 to 2010.
Willis Nelson Dysart was an American mental calculator. His talent for arithmetic emerged at the age of three after his mother taught him to count. He quit school in the third grade and pursued a career as a lightning calculator.
Jorge Arturo Mendoza Huertas is a Peruvian mental calculator.
Scott Flansburg is an American dubbed "The Human Calculator" and listed in the Guinness Book of World Records for speed of mental calculation. He is the annual host and ambassador for The National Counting Bee, a math educator, and media personality. He has published the books Math Magic and Math Magic for Your Kids.
Dr Amit Garg is an Indian mathematician and mental calculator. He currently works as founder and CEO at ORMAE, a firm registered in USA, UAE & India which engages in building innovative products, consulting and training in Operations Research and Data Science.
Lee Jeonghee is a South Korean abacus master. She is the only known soroban abacus master to have reached the eleventh dan. She is also known as Abacus Master (주산왕) in South Korea.
