![]() ![]() Though it can not do what calculators do, it can serve its purpose in many ways like accounting forĪnimals they killed and recording and storing details they gathered in computing.Ĭlick here to see some of our favorite Abacus designs.– Opens in new tab. This shows the concept that a simple idea can manifest complexities in its usage. The truth is, suànpán was built to handle operations like division, addition, multiplication, subtraction, and even square root and cube root. ![]() More so in resetting the tool, the abacist or the abacus user executes a quick shaking of the suànpán along the horizontal axis to move all the beads away from the center of the horizontal beam. You compute the value of something you are counting when you move the beads higher and you do not count the value when you move the beads down. The counting of the beads or the computation is done by moving each bead in either an up or down manner towards the beam. The typical suànpán had more than seven rods wherein two beads are on each rod in the higher deck and five beads in the bottom for decimal and hexadecimal calculation. The suànpán or the Chinese counting frame was a 20-centimeter in height and its width since it depends on the preference of the user. Since the Chinese abacus was very handy, it was no surprise that it was successfully proliferated in other countries ever since they learn the power of the tool which was made out of simple yet very effective in doing arithmetic processes. This form of computing device was created using wood and beads. And since the Chinese are known to relate their ways of like to their environment the attributes such as the top and bottom are considered heaven and earth respectively. So for the record, the existence of Chinese abacus can be dated back to the 14 century A.D. In China, for example, the idea of calculators, computers, and other computing machines had been seen in the earliest form of counting device they had (apart from the fingers people have), known to modern people as the abacus. Scholars of this camp also cite many other literary descriptions of the abaci as evidence.Though ancient people weren’t able to have the technology that we have today, they, however, were as innovative as we are right now. ![]() They cited the note of a Yuan Writer named Tao Zongyi, who portrayed in his book that “unlike the newly-bought servants, the experienced ones were just like abacus beads they wouldn’t move unless you poked them to.” The analogy demonstrated that the using of the abacus was probably very common at that time. Then there came a second camp who believed that the abacus was invented in the middle period of the Yuan Dynasty (1206AD-1368AD) and became widely used in early Ming Dynasty (1368AD-1644AD). But other scholars disapproved this assertion by classifying the mentioned tool as a gadget used only for addition and subtraction. In this book, Xu recorded fourteen ways of calculation, among which there was a description of a way of computation by moving beads within three beams. Their proof was the book A Gleaning of Arithmetic (Shu Shu Ji Yi) by the mathematician Xu Yue (?-220AD). Firstly, starting in the Qing Dynasty, a group of people advocated that there had been documents on abaci since the Han Dynasty (202BC-220AD). ![]()
