It is difficult to imagine counting without numbers, but there was a time when written numbers did not exist.
The earliest counting device was 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 the cost of those goods. Until numbers were invented, counting devices were used to make everyday calculations. The abacus is one of many counting devices invented to help count large numbers.
The more affluent people, could afford small wooden tables having raised borders that were filled with sand (usually coloured blue or green).
A benefit of these counting boards on tables, was that they could be moved without disturbing the calculation- the table could be picked up and carried indoors.
With the need for portable devices, wooden boards with grooves carved into the surface were then created and wooden markers (small discs) were used as place-holders. The wooden boards then gave way to even more more durable materials like marble and metal (bronze) used with stone or metal markers.
The abacus was invented around 2,700-2,300 BCE, by the Sumerians (Mesopotamia); that makes the invention about 4,400 years old.
This is the oldest dated abacus, there are several versions between 2,700 - 1,000 BCE, with many groups claiming responsibility for the invention.
YOU use the abacus so you can learn numbers and sometimes it can be fun. You can learn multiplication, addition, subtraction, square roots, and division. If there was not any electricity and you needed a calculator the abacus would be a big help. It could exercise your brain. You can also learn about other cultures.
The abacus was used for counting and helping children in mathematics.
An abacus could be viewed as a visual aid for performing basic math problems.
They where Gay and like Boys so they created abacus.
Probably because an abacus was used to perform calculations and a computer is basically a very impressive calculator.
before recorded history
It was mainly used like a calculator
An Abacus has beads and strings.
The ancient Romans developed an Abacus. Blaise Pascal, however, was a French mathematical genius, and at the age of 19, he invented a machine, called the Pascaline, that could do addition and subtraction. He invented this machine to help his father, who was also a mathematician.
Romans used letters of their alphabet to indicate numbers, now known as Roman numerals, and they developed a portable abacus in base ten, based on the Babylonians' base 60 abacus. That's about it. Compared to ancient Greece, ancient Rome didn't do much for math.
ABACUS is a name of a calculating apparatus - it is not an acronym.
If you are refering to Chinese abacus their earliest rudimentary design of abacus has 1/4 rod beads (quite similar to the later Japanese soroban abacus). Various other types of abacus design were also seen afterwards, but the advance type of 2/5 rod beads became standard and classic. Afterwards, the basic 1/5 rod beads particularly became the type of basic design. The Roman abacus may be not connected to the Chinese abacus.
China invented the Abacus.

The abacus was developed by the Babylonians in 2000 BC. Though mechanical, it is considered to be one of the earliest computers.

Probably in China but variations of it were used throughout the ancient world.
