The abacus was a table of successive columns with beads or stones representing a single unit, which could be used for addition or subtraction. Other cultures altered and refined the abacus; the Chinese, for example, put beads on wire within a bamboo frame to enhance ease of use. Unfortunately, the abacus was not very useful for multiplication or division, necessitating the invention of a new and more sophisticated device.
The Pascal calculator, invented by French inventor and mathematician Blaise Pascal, was lauded for attempting arithmetic calculations previously thought impossible. But unfortunately, they were difficult to produce and very few were ever made. It was designed by an American Arithometer Co. It was proved an inaccurate calculating machine.
Later on, after more research, Burroughs received another patent for an improved calculating device in In earlier technology, either the calculators have beads or any handle to rotate or a sliding disk. In the late 18th century and early 19th century , all the inventors were focusing on the design part of the calculator. They were trying to simplify it. So in , the new technology was invented in a calculator.
The mathematicians installed the push-button technology in the calculators. These pushbuttons are still found in the mechanical calculator. That technology was a huge step in the direction of simplifying the machine. After the invention of pushbuttons , Dalton Adding Machine was the first calculator having ten keys.
It was invented by James L. Dalton in It was the most popular 10 key adders of that time. Many other calculator models had inspired by the design of Dalton's Machine. It was the company that designed calculators or adding machines. Victor Adding Machine Co.
It was established in Chicago. Oliver David Johantgen , the chief designer and other three owners. It was designed for mainly shopkeepers and business owners. There was a reel of paper fixed in the machine. It means this calculating machine was printable. The mechanical calculator was invented in the mid-nineteenth century b y Thomas de Colmar. After such a large calculator, it was time to introduced something new, the first Pocket Calculator. It was designed by Curt Herzstark in This calculator was a handheld machine that was known for its immense compact design.
The Curta calculator was a small cylindrical-shaped machine that can easily fit in the palm of your hand. At that time, it was a very useful tool for accountants and engineers.
It was invented on February 15, , at the University of Pennsylvania. It was known by the name of 'GiantBrain'. ENIAC was the first programmable, electronic, large-scale, general-purpose, and digital computer.
It was capable of solving huge and complicated problems in a fraction of seconds. It could perform basic arithmetic operations such as addition, subtraction, multiplication, and division. It was times faster than the earlier electronic mechanical calculators. In electronic calculators, the operation performs with the help of electronic signals. These signals are transmitted between the sender and the receiver. It was the first calculator which was all electronic. It means all the parts and processes of the calculator were electronic except the push button keys which were mechanical only.
It was invented in In Britain which was led by Norbert Kitz. Its name was exactly matched with its features. Fact 7: Who invented the Calculator?
Willhelm Schickard invented a calculating machine, called by his contemporaries the 'Speeding Clock' or 'Calculating Clock', the first mechanical calculator that used gears for the addition, subtraction and multiplication of six-digit numbers.
Fact 8: Who invented the Calculator? Pascal's Calculator, known as the arithmetic machine and later as the Pascaline was invented by Blaise Pascal in when he was 19 years old. Fact 9: Who invented the Calculator? Fact Who invented the Calculator? Blaise Pascal was provided with an excellent home education by his father, Etienne Pascal, was presiding judge of the tax court at Clermont-Ferrand.
The Pascaline machine was received to great acclaim by the scientists and mathematicians of the era. The Pascaline calculator could add, subtract, multiply, and divide and was housed in a compact brass box that measured 13 inches by 4ins by 2 ins mm by mm by 75mm.
The Pascaline had metal wheel dials that were turned to the appropriate numbers using a stylus. The answers appeared in boxes in the top of the calculator.
The Pascaline was the first commercially produced calculator and it came in both decimal and non-decimal varieties. Blaise Pascal sold twenty of his machines but ceased production in because they were not cost effective to produce. Other calculating machines were developed but none became commercially viable until Charles Xavier Thomas de Colmar - developed his simplified 'arithmometer'.
The 'arithmometer' was invented in and manufactured from to This was the world's first all-electronic desktop calculator and it was developed in Britain by Control Systems Ltd. ANITA used the same push button key layout as the company's mechanical comptometers, but these were the only moving parts. All the rest was done electronically, using a mix of vacuum and cold cathode 'Dekatron' counting tubes. The illuminated place display was provided by 'Nixie' glow discharge tubes.
Four of these Beatles-era transistorised calculators were especially significant, including Toshiba's "Toscal" BC calculator, which was remarkable in using an early form of Random Access Memory RAM built from separate circuit boards.
The Olivetti Programma introduced in late was an elegant machine that won many industrial design awards. It could read and write to magnetic cards and display results on its built-in printer.
As a desktop electronic calculating machine that was programmable by non-specialists for individual use, the Programma could even claim to be the first personal computer. Built like a T tank and weighing around 8 kg, this was the first calculator in the world to include a square root function. All electronic calculators to this point had been bulky and heavy machines, costing more than many family cars of the period. However in , Texas Instruments released their landmark " Cal Tech " prototype, a calculator that could add, multiply, subtract, and divide, and print results to a paper tape while being compact enough to be held in the hand.
