![]() The Pascal calculator, invented by French inventor and mathematician Blaise Pascal, was lauded for attempting arithmetic calculations previously thought impossible. In 1642, the first true “calculator” was invented: one that performed calculations through a clockwork-type of mechanism. While these devices greatly assisted calculations, they were not true “calculators,” merely assisting the person doing the mental calculation. The “bones” are thin rods, which are inscribed with multiplication tables, and the user determines their sum by changing the vertical alignment of the rods, and horizontally reading the multiplication tables. Unfortunately, the abacus was not very useful for multiplication or division, necessitating the invention of a new and more sophisticated device.įast forward 4,500 years to 1617, when Scottish mathematician John Napier published Rabdology, or “calculation with rods.” In his writing, Napier described a device that came to be known as Napier’s bones. Other cultures altered and refined the abacus the Chinese, for example, put beads on wire within a bamboo frame to enhance ease of use. The abacus was a table of successive columns with beads or stones representing a single unit, which could be used for addition or subtraction. The first tool created specifically for use in mathematical computations was the abacus, likely invented in Sumeria around 2500 B.C. But that doesn’t mean that mathematical tools were not available before the 20 th century-there were many different computing machines created long before digital calculators and smartphones. That being said, the calculators we know today were not invented until the 1970s, and the use of smartphones as calculators did not begin until at least the late nineties. It is almost impossible for us to imagine mathematics without something as seemingly simple as a calculator. Here, the professionals at Techmart take you through the history of the calculator, and how we came to have the ubiquitous devices we use every day.

On each rod, the classic Chinese abacus has 2 beads on the upper deck and 5 on the lower deck such an abacus is also referred to as a 2/5 abacus. The device was made of wood with metal re-inforcements. The abacus, called Suan-Pan in Chinese, as it appears today, was first chronicled circa 1200 C.E. In which country was the abacus invented? ![]() The Ming Dynasty lasted from 1388 to 1644 and was a period of cultural exchange and economic prosperity, at least in part. According to Chinese history, the abacus as we know it was invented sometime during the Ming Dynasty by mathematician Cheng Dawei. The Scot, John Napier, invented these strips (originally made from bone) about 400 years ago to help calculate multiplication and division.ġ China. Some historians believe that the abacus was invented by the ancient Chinese while some believe that it was invented by the Babylonians or the Egyptians. It is presumed that the earliest abacus was invented about 5000 years ago.
