What is Abacus?
ABACUS is a form of hand -operated computer aids that have existed for thousands of years. Abacation continues to be used in parts of Asia and the Middle East, especially in stores, and can often be obtained in stores that store Chinese or Japanese goods. In the West, it is sometimes used as an educational tool that helps small children to understand numbers and some mathematicians enjoy experimenting with Abacus to solve simple problems.
The design of ABAC varies, depending on the area of the world from which it is, but generally consists of a framework that supports sticks or wires. The rods hold beads that can be moved on the frame to represent different numbers. In some cases, Abacus Crossbeam, which divides bars; The beads above the beam are multiples of five, while the below are multiples of one. Each rod represents a decimal place. The Greeks used the plate cover in the sand to pull out equations when they worked on them, and probably raised their habit from Jews who used the word abaq to describecomputer boards. The Greeks and the Romans used different forms of Abacus; For example, the Romans preferred boards with grooves and beads or rocks. It seems that the style of counting with rods and beads originated in China.
An experienced abacist can calculate a number of basic mathematical functions on Abacus. Adding and subtraction is obviously relatively simple, but the tool can also be used to divide and multiply the numbers and to find square or cubic roots. Many visitors to Chinese shops are familiar with the clicks on the sounds of Abacus, as well as the sudden rattle that occurs when one is shaken to reset it back to zero.
essentially, ABACUS can be considered a visual aid to perform basic pads, such as prolonging fingers and leg counting. To use Abacus for functions such as search of cube roots; It is possible to find a manual for performing such calculations using TOhoto tools in a bookstore. In addition to finding Abac, available for shopping in stores that specialize in Asian products, it is also possible to create one with a text in order to help determine the style.
