The abacus is still used to teach the fundamentals of mathematics to children in most countries.ĭesigns such as the Japanese soroban have been used for practical calculations of up to multi-digit numbers. In the ancient world, particularly before the introduction of positional notation, abacuses were a practical calculating tool. Abacuses are still made, often as a bamboo frame with beads sliding on wires. Later the beads were made to slide on rods and built into a frame, allowing faster manipulation. In their earliest designs, the rows of beads could be loose on a flat surface or sliding in grooves. One of the two numbers is set up, and the beads are manipulated to perform an operation such as addition, or even a square or cubic root. It consists of rows of movable beads, or similar objects, strung on a wire. The exact origin of the abacus has not yet emerged. It was used in the ancient Near East, Europe, China, and Russia, millennia before the adoption of the Hindu-Arabic numeral system. The abacus ( plural abaci or abacuses), also called a counting frame, is a calculating tool which has been used since ancient times. There was keen competition between the two from the introduction of the Algebra into Europe in the 12th century until its triumph in the 16th. The woodcut shows Arithmetica instructing an algorist and an abacist (inaccurately represented as Boethius and Pythagoras).

We seek to retell the story of our beginnings."Abaci" and "Abacuses" redirect here. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.īy bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe. And while some people may seem content with the story as it stands, our view is that there exist countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained. The earliest known written documentation of the Chinese abacus dates to the 2nd century BC.Īt Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. The beads are moved up and down during calculations.Īccording to legend, the Chinese abacus (‘suan pan’ or ‘zhusuan’) was invented by mythical Yellow Emperor (Huangdi), father of Chinese civilization. There are five beads on each rod on the bottom deck, known as earth. The upper deck, which is known as heaven, has two beads on each rod. The typical abacus has a hardwood frame and hardwood beads, with two decks and more than seven rods. Now this ‘ancient computer’ has received credit for its historical and cultural importance by being added to the world intangible cultural heritage list. Some devices can be quite large and complex.
It can be used for high-speed addition, subtraction, multiplication, division, square roots, cube roots and other calculations. The abacus, also called a counting frame, is a calculating tool that was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere.
