The fra
18、me 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 into two sections, known as the upper deck and the lower deck.The standard abacus can be used to perform addition, subtraction, division and multiplicat
19、ion. The abacus can also be used to extract square-roots and cubic roots.The abacus is prepared for use by placing it flat on a table or ones lap and pushing all the beads on both the upper and lower decks away from the beam. The beads are manipulated with either the index finger or the thumb of one
20、 hand. Each bead in the upper deck has a value of 5; each bead in the lower deck has a value of 1. Beads are considered counted, when moved towards the beam that separates the two decks. After 5 beads are counted in the lower deck, the result is “carried” to the upper deck; after both beads in the u
21、pper deck are counted, the result (10) is then carried to the left-most adjacent column. The right-most column is the ones column; the next adjacent to the left is the tens column; the next adjacent to the left is the hundreds column, and so on.

The earliest counting device was t
23、he 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 the cost of those goods. Until numbers were invented, counting devices were used to make everyday calculations. Step HomeworkAsk the students to summarize what they have learnt in the unit and prepare for the next unit.
