18、 was found in Western countries. A sample version: The abacus is typically constructed of various types of hardwoods and comes in various sizes. The frame of the abacus has a series of vertical rods on which a number of wooden beads are allowed to slide freely. A horizontal beam separates the frame
19、into two sections, known as the upper deck and the lower deck. The standard abacus can be used to perform addition, subtraction, division and multiplication. The abacus can also be used to extract square-roots and cubic roots.The abacus is prepared for use by placing it flat on table or ones lap and
20、 pushing all the beads on both the upper and lower decks away from the beam. The heads are manipulated with either the index finger or the thumb of one hand. Each head in theupper deck has a value of 5; each beads in the lower deck has a value of 1. Beads are considered counted, when moved towards t
21、he beam that separates the two decks. After 5 heads are counted in the lower deck, the result is carried to the upper deck; after both heads in the upper deck are counted, the result 10 is then carried to the left-most adjacent column and so on. Floating point calculations are performed by designati
22、ng a space between 2 columns as the decimal-point and all the rows to the right of that space represent fractional portions while all the rows to the left represent whole number digits. The abacus is one of many counting devices invented to help count large numbers. The earliest counting device was
23、the human hand and its fingers. Then, as larger quantities (larger than ten human fingers could represent) were counted, various natural items like pebbles and twigs were used to help count. Merchants who traded goods not only needed a way to count goods they bought and sold, but also to calculate t
24、he cost of those goods. Until numbers were invented, counting devices were used to make everyday calculations. Step5.Testing in class & improving skills（随堂检测，落实考点） Task3.
