The Abacus: A Brief History

Right below this crack, we come across another set of eleven parallel lines which are again divided into two sections by a line that is perpendicular to them but has a semi-circle at the top of the intersection. The third, sixth and ninth lines are marked with a cross where they go and intersect with the vertical line. The Hindu-Arabic number system made counting, calculating and record-keeping a lot easier than with counting boards which had all but disappeared in Western Europe by the 14 century. Arithmetic brought about the invention of logarithms by John Napier and logarithmic scales by Edmund Gunter. In 1622, William Oughtred used these two inventions together and invented the slide rule which lasted until modern times when the scientific calculator became popular in the early 1970s.

Abacus Counting

The device consists of a series of beads on parallel wires that are arranged in three separate rows. The beads in the Abacus represent a switch on the Computer in either an “on” or “off” position. Abacus is a man-made calculating device invented around 5000 years ago. According to Historians, it was the Chinese people who invented Abacus around 500BC.

Chinese Abacus

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.

When the right hand is used on the abacus, the left side cells of the brain are activated. The left-brain activity is interpreting, and the right brain activity is visualizing. Therefore, both the left and right sides of the brain work commonly and help to whole-brain development. This is known to be the modification of the current Abacus to support the learners that have vision disabilities. The learners can manipulate the beads that would in effect help them in the in-depth understanding of the numbers. This Abacus can be used to calculate various numbers involving arithmetic processes like addition, subtraction, division or multiplication.

History and Origins of the Abacus

Do the same thing in the ones place, “borrowing” a bead from the tens place (making it 6) to subtract 7 from 12 instead of 2. Eight removed from nine is one, so a single abacus market reviews bead is left up in the hundreds place. It is easier to use one’s thumb to move the beads in the top row, and the index finger to move the beads in the bottom row.

The evolution of the counting device can be divided into three ages: Ancient Times, Middle Ages, and Modern Times.

Due to fundamental similarities in their core functions, computers are sometimes referred to as an abacus due to their striking resemblance. More recently, the use of the abacus has been shown to produce a number of changes in the grey matter and brain matter, helping to maintain integration and accelerate learning through training. It also helps us to solve arithmetic problems through calculation and memory, as long as the operations are done with simple numbers. Today, this ancient instrument is used as a type of didactic toy to teach mathematics in a simple way to children, as it functions as a multiplication table. This calculating tool uses a counting frame and a series of beads on an upper and lower set of rods. Beads are pushed to the center to mark numbers in different place values, making it easy to make complex calculations.

Who Used the First Abacus to Count?

Digital devices need not replace manipulative tools like the abacus that build mathematical thinking. Overall, an abacus provides a straightforward way to calculate and teach arithmetic using visual and spatial representations. The bead above the bar has a value of 5, while the lower bead has a value of 1. By sliding the beads up and down, you can represent any number and perform arithmetic through a place value system. In Western countries, a bead frame similar to the Russian abacus but with straight wires and a vertical frame is common (see image). It had a close relation to natural phenomena, the underworld, and the cycles of the heavens.

• Each rod typically represents one digit of a multi-digit number laid out using a positional numeral system such as base ten (though some cultures used different numerical bases).
• This Abacus is still in use, however, it is overshadowed by the use of electronic calculators.
• Each rod consists of beads, which we can move up and down, with the help of the index and the thumb finger.
• Then, as even larger quantities (greater than ten fingers and toes could represent) were counted, various natural items like pebbles, sea shells and twigs were used to help keep count.
• The term originated with the Arabic ‘abq’, which refers to dust or sand.
• The lower line is simply subtracted from the upper.” —The Dialogue on the Exchequer, 1177.
• The introduction of the Hindu-Arabic notation, with its place value and zero, gradually replaced the abacus, though it was still widely used in Europe as late as the 17th century.
• The abacus is typically constructed of various types of hardwoods and comes in varying sizes.

Types of Abacuses

Educated guesses can be made about the construction of counting boards based on early writings of Plutarch and others. Many study’s have shown that no one in particular has made the abacus but many believe it was made in China. An adapted abacus, invented by Tim Cranmer, called a Cranmer abacus is still commonly used by individuals who are blind. A piece of soft fabric or rubber is placed behind the beads so that they do not move inadvertently.

Counting

It is an instrument that helps us perform simple mathematical operations and a little algebra. Mesopotamia – The earliest archaeological evidence of a counting board device dates back to 2700–2300 BCE from the Sumerian civilization in ancient Mesopotamia. These early abacuses paved the way for the development of the Roman abacus many centuries later. One example of archaeological evidence of the Roman abacus, shown nearby in reconstruction, dates to the 1st century AD. It has eight long grooves containing up to five beads in each and eight shorter grooves having either one or no beads in each.

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.

Europe – Roman and Greek abacuses date from around the 4th century BCE. Early European abacuses used grooved channels and stones instead of beads. The Nepōhualtzintzin was divided into two main parts separated by a bar or intermediate cord. Beads in the first row have unitary values (1, 2, 3, and 4), and on the right side, three beads had values of 5, 10, and 15, respectively. In order to know the value of the respective beads of the upper rows, it is enough to multiply by 20 (by each row), the value of the corresponding count in the first row. With the help of visualizing abacus bead movements, children can solve calculations in their minds speedily.

Evolution of Counting Devices

Discover Abacus, and uncover the intricacies of this versatile tool as we delve into its definition, explore the different types, and trace its fascinating historical evolution. Join us in unlocking the secrets of the abacus, a tool that has stood the test of time in shaping our understanding of numbers. The Chinese Abacus, or the suanpan, is the most widely used and recognizable type of Abacus. It has two beads on the top row and five beads on the bottom row, and each dot on the top row represents five, while each bead on the bottom row represents one. The Japanese Abacus, or soroban, has a similar design but has one dot on the top row and four beads on the bottom. The Russian Abacus, or school, has ten beads on each row, with the beads on the top row representing five while the dots on the bottom row represent one.

Some historians believe that the abacus was the first instrument created to perform calculations. Invention and technological innovation have relegated the use of the abacus and caused it to lose popularity in schools and homes, where it was previously used to educate children. As Abacus became more widespread, various versions of the device emerged in different parts of the world. For example, the Roman Abacus, used in ancient Rome, was similar to the Chinese Abacus but had slight differences in design.

Its origin is unknown, but it is known that in ancient times, people used materials to count, according to what has been historically discovered. Although largely replaced by electronic devices, abacuses are still used for low-tech computations in settings where electricity may not be available. In addition, they are widely used as teaching tools, especially in Asia, and by the visually impaired, who may have difficulty reading the screen of an electrical calculator. Looking forward, the abacus may find new popularity as a visual-tactile teaching tool. Recent studies show using an abacus enhances math skills and mental math ability even in children already comfortable with computers. Abacus is a vital computing device used by students and professionals working in mathematical areas.This article gives a brief view of the abacus.

More Powerful than a Calculator

• The modern abacus is attributed to Tim Cranmer, who invented the Cranmer abacus in 1962.
• The beads are counted when they move towards the reckoning bar, and if any bead does not touch the reckoning bar, that column contains value zero.
• Each rod represents a place value, with the rightmost rod representing the ones place.
• Today, the Abacus is still widely used in some parts of the world, especially in Asia, to teach children how to perform mathematical calculations.
• In Western Europe, as arithmetic (calculating using written numbers) gained in popularity in the latter part of the Middle Ages, the use of counting boards began to diminish and eventually disappear by 1500.
• The abacus has endured all this time because of its power — both as a calculator, and as a tool for enrichment.

In the Middle Ages, the Abacus was further developed in Europe, and merchants and traders used it for bookkeeping and accounting. In the 17th century, the Abacus was introduced to Japan, where it was embraced and further refined, resulting in the development of a unique style of Abacus called the Soroban. Today, the Abacus is still used in many parts of the world, particularly in Asia, as a teaching and learning arithmetic tool.

A brain takes input from the organs; thus, in an abacus, the beads are arranged in that way. When the children manage it by their fingers, the nerve endings get activated and then it activates the cells which are in the brain. When the left hand is used, the cells on the right side of the brain are activated.

There are various courses offered online or in schools for learning abacus. The term “computer” initially referred to individuals performing calculations manually using an abacus as their primary tool for computation. With technological progress came mechanical calculators and, eventually, electronic computers that built upon its principles.

In 1972 the Hewlett Packard HP-35 scientific calculator made the slide-rule obsolete. The abacus is still in use today by shopkeepers in Asia and “Chinatowns” in North America. The abacus is still taught in Asian schools, and a few schools in the West. Blind children are taught to use the abacus where their sighted counterparts would be taught to use paper and pencil to perform calculations. In 1958 Lee Kai-chen published a manual for his “new” abacus designed with 4 decks (it combines two abaci; the top abacus is a small 1/4 soroban and the bottom one is a 2/5 suan-pan). According to the author, multiplication and division are easier using this modified abacus and square roots and cubic roots of numbers can be calculated.

The Babylonians, Ancient Chinese, Japanese and Russians all used a calculating tool similar to a modern-day abacus. As the most ancient calculator known, the origin and inventor of the abacus is unknown. It’s been used for centuries in China and has a long history of use in Ancient Greece, Rome, Russia Japan, and Babylon. Abacus can be learnt at any age, but it is always preferred that the children are introduced to the Abacus at a very young age.

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.
