The number 9 is the maximum number of beads on an abacus because it is the last number in the ones place before the tens place is reached.. The abacus is a tool that was used for arithmetic in ancient times. It is composed of a frame with a series of rods or wires on which beads are strung. The beads are used to represent numbers.
You can use an abacus to add and subtract quantities of beads by moving the them around. This can in turn help to solve equations involving counting numbers.
Abacus, also known as a counting frame, is used (mainly) in Asia. Beads on wires, wooden dowels, etc, are representative of numbers.
The numerical value represented on the abacus depends on the position of the beads. Each column on the abacus represents a place value, ranging from units to thousands. By moving beads up or down within each column, different numerical values can be represented.
An abacus is a mechanical tool that is used to count the numbers. It was originally made up of wood that has several beads that moves up and down through strings or sticks in the frame.

An abacus is a mechanical device for performing arithmetical calculations. Abaci are usually a wooden frame with beads used to represent numbers.
You can use an abacus to add and subtract quantities of beads by moving the them around. This can in turn help to solve equations involving counting numbers.
The difference is that an abacus uses beads to calculate. A calculater uses solar energy or batteries to make its digital numbers. In other words an abacus uses beads and a calculater uses buttons you press to put numbers on the calculaters screen.
Abacus, also known as a counting frame, is used (mainly) in Asia. Beads on wires, wooden dowels, etc, are representative of numbers.
An abacus is a counting device that uses beads on a table or string that represent numbers. The device is divided into columns, each column representing a multiple of 10 (x10, x100, x1000 etc.) and each column has 10 beads in it. This enables numbers to be formed by rearranging the beads, this means that simple and complex arithmetic can be performed on the abacus. The abacus was invented around 2,700-2,300 BCE, by the Sumerians (Mesopotamia) ; that makes the invention about 4,400 years old
