What are the features of the abacus?

Answer 1

1. The abacus is portable, unlike its predecessors the sand board and the counting board (these worked the same way as the abacus except the beads sat in slots on a stationary horizontal surface instead of being strung on wires).
2. The abacus allows relatively rapid addition and subtraction of much larger numbers than is easy to do mentally.
3. An illiterate merchant (or other person) can rapidly learn how to operate an abacus for common daily calculations.
4. The abacus is easy to make, no special skills or knowledge are needed.
5. etc.

Answer 4

The abacus is a manual calculating device that consists of a frame with rods or wires on which beads are moved to represent numbers. It typically has multiple columns representing different place values, such as units, tens, hundreds, etc. The beads on each rod can be moved up or down to perform addition, subtraction, multiplication, and division operations. The abacus is a versatile tool that can be used for basic arithmetic calculations and is particularly useful for teaching mathematical concepts and improving mental math skills.
