These days people rely on calculators on their computers and cell phones.

Who Used the First Abacus to Count?

Compare the quick rate of progress in last one-thousand years to the slow progress during the first one-thousand years of civilization. Merchants who traded goods needed a way to keep count (inventory) of the goods they bought and sold. Various portable counting devices were invented to keep tallies. The abacus is one of many counting devices invented to help count large numbers. When the Hindu-Arabic number system came into use, abaci were adapted to use place-value counting. The abacus is a very old calculus tool, which has been adapted by a large number of cultures.

Abacus is a device consisting of a frame with rows of wires consisting of beads. It is a hand-operated device used for calculation and is bound to have some human error. It can be used for performing calculations such as multiplication, addition, and division. Earlier operations like counting were performed on hands or using Vedic maths but larger operations require more calculations. Therefore there was a need for a development tool for such calculations. It was India’s first calculator used in Asia, Europe, and Russia.

The Salamis Tablet is made from a white marble that measures 149 cm in length, 75 cm in width, and 4.5 cm in thickness. At the centre of the Tablet, there are a set of five horizontal parallel lines that are divided equally with the help of a perpendicular vertical line. This is capped with a semicircle right at the intersection of the horizontal line and the vertical line at the bottom. One would notice a wide space that has a horizontal crack dividing it.

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. Probably their beginning was in flat stones with stones that could be moved to count. Some historians consider that the origin of the abacus is Chinese because it is the place where this instrument is more remarkable. It is also believed that the Dameros used the abacus in sand and rocks to perform arithmetic calculations.

The Abacus is an incredibly versatile tool that can help children learn math concepts, improve mental calculation skills, and develop logical thinking abilities. Moreover, it has been an essential tool for traders, accountants, and merchants. An abacus is a manual calculating device used since ancient times. It is a rectangular frame with rows of beads or stones that slide along rods or wires. The Abacus is designed to perform addition, subtraction, multiplication, and division operations.

The Chinese abacus was known as the suanpan, it is believed to have been in use since at least the 2nd century BCE. It is believed that Mesopotamia used an abacus for going back during 2700 B.C. Additionally, it was also used in other civilizations such as Greek, Egyptian, Chinese, Persian, Roman, etc. The invention of a numeral system allowed numbers to be broken up into units, tens, hundreds, and so on.

This Abacus is still in use, however, it is overshadowed by the use of electronic calculators. The Abacus is constructed of various types of hardwoods and comes in various sizes. The frame consists of a series of vertical rods on which several wooden beads are allowed to slide freely. A horizontal beam is used to separate the frame into two sections i.e the upper deck and the lower deck. Each rod consists of beads, which we can move up and down, with the help of the index and the thumb finger. Fibonacci learned of the Arabic numbering system when he accompanied his father, a merchant, to various Arab ports in the Mediterranean Sea.
