what is meaning of abacus?

Answer 1

An abacus is a calculation tool, often constructed as a wooden frame with beads sliding on wires. It was in use centuries before the adoption of the written Hindu-Arabic numeral system and is still widely used by merchants and clerks in the People's Republic of China, Japan, Africa, and elsewhere.

The plural of abacus is abaci.
The origins of the abacus are disputed, as many different cultures have been known to have used similar tools. It is known to have existed in Babylonia and in China, with invention to have taken place between 1000 BCE and 500 BCE. The first abacus was almost certainly based on a flat stone covered with sand or dust. Lines were drawn in the sand and pebbles used to aid calculations. From this, a variety of abaci were developed; the most popular were based on the bi-quinary system, using a combination of two bases (base-2 and base-5) to represent decimal numbers.

Answer 3

Abacus refers to a sand covered table upon which figures were inscribed using a stylus. There is a suspicion that the abacus had a semitic origin.

The counters were arranged loosely along lines or placed in grooves.

I think they showed one in "Beautiful Minds," with Russell Crowe. If it's the movie I'm thinking of, the character "challenges" an Asian man to calculate problems, one with the abacus, the other with just his mind. Simple problems were done faster with the abacus. Rational numbers and further calculations were better done in Russell's character's head.
