However, China and Japan have the longest history of consistent abacus use and development. An abacus is a manual calculating tool used for adding, subtracting, multiplying, and dividing. Each rod represents a place value, with the rightmost rod representing the ones place. You can visualize numbers and calculate by manipulating the beads along the frame.
Renaissance abacuses
The abacus frame has a series of vertical rods on which a number of wooden beads are allowed to slide freely. A horizontal beam separates the structure into two sections, known as the upper deck and the lower deck. Monikered as ‘The First Calculator,’ this nifty device allowed ancient scholars to perform large digit numerical operations with ease, long before the invention of the written numerical system. The abacus is an instrument made of wood that has a series of strings or wires placed in parallel and each string has ten beads or balls that have mobility.
Portable Computing Devices Today
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.

- One example of archaeological evidence of the Roman abacus, shown nearby in reconstruction, dates to the 1st century AD.
- If you do not want to start counting from the far right, these markers (separation dots and off-colored beads) have the ability to mark your first position.
- The wooden boards then gave way to even more more durable materials like marble and metal (bronze) used with stone or metal markers.
- These early abacuses paved the way for the development of the Roman abacus many centuries later.
- Over it is spread a cloth, bought in Easter term, with a special pattern, black, ruled with lines a foot, or a full span, apart.
- The invention of a numeral system allowed numbers to be broken up into units, tens, hundreds, and so on.
Each rod represents a different place value—ones, tens, hundreds, thousands, and so on. The abacus tool can perform the foundational arithmetic operations of addition, subtraction, multiplication, division, both at a small scale and with large digit inputs. Moreover, as users progress, they can easily execute long division and negative number operations. Chinese culture uses the suan pan to serve a similar function, featuring beads arranged above and below each horizontal bar on every rod.
Where Are Abacuses Used Worldwide?
After learning the basics of counting on the abacus, you can quickly perform arithmetic like addition, subtraction, multiplication, and division. Long before the invention of the electronic calculator or the computer, people counted and did calculations with a device called an abacus. On this instrument, calculations are made with beads, or counters, instead of numerals. The beads that slide along a series of wires or rods set in a frame to represent the decimal places.

So, the farthest column on the right would be the “ones” place (1-9), the second farthest the “tens” place (10-99), the third farthest the hundreds ( ), and so on. Even today, in the modern world of computers and calculators, it is used by traders, merchants, etc. in many parts of the world. The term originated with the Arabic ‘abq’, which refers to dust or sand.
SOROBAN
In the 21st century, portable counting devices rarely exist as separate entities. Instead they are simulated as Apps running on desktop computers, smartphones and tablets. Civilization, which began recording history with a stylus and a clay tablet thousands of years ago is re-using those original terms today. In the Middle Ages, wood became the primary material for manufacturing counting boards; the orientation of the beads also switched from vertical to horizontal. 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. Both the abacus and the counting board are mechanical aids used for counting; they are not calculators in the sense we use the word today.
When was the Abacus first Invented?
- 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.
- The design of the schoty is based on a pair of human hands (each row has ten beads, corresponding to ten fingers).
- There are many ways to say the word abacus, for example, in Chinese it is pronounced Suan Pan, in Japanese Soroban, in Korean Tschu Pan, in Hebrew Jeshboniá and in Russian Schoty, to mention some examples.

The abacus has endured all this time because of its power — both as a calculator, and as a tool for enrichment. So this ancient calculating device continues to build valuable skills relevant today. While less common in most of the world, it remains ingrained in Asian culture. Egypt – Ancient Egyptians used a primitive device involving a slab of stone covered with sand for making calculations as early as the 2nd millennium BCE.
The earliest counting boards are forever lost because they were constructed of perishable materials like wood.
As time passed, the design of an Abacus kit has widely varied in terms of style, size and material but the design of Abacus kits remains to be in a combination of rods and pebbles. Deriving inspiration from Chinese Suanpan, Soroban came into existence in the 14th century. The beads in the Japanese Soroban are made from wood and bamboo rods to slide up and down.

The person operating the abacus performs calculations in their head and uses the abacus as a physical aid to keep track of the sums, the carrys, etc. 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, capable of counting up to 10 things; toes were also used to count in tropical cultures.
This was a finger abacus, on one hand, 0, 1, 2, 3, and 4 were used; and on the other hand 0, 1, 2, and 3 were used. Note the use of zero at the beginning and end of the two cycles. It is believed that the first abacus was made by Ancient Mesopotamians of Sumeria .
The Suan-pan, the Soroban and the Schoty are from the period c. 1200 A.D to the present.
The other most popular Abacus in use is Sorobon or the Japanese Abacus. The exact date of the invention of the original counting frame is unknown. The abacus is believed to have been invented between 2,700 BC and 300 BC. The abacus is also an ancestor of the modern calculator and computer. Binary digit, the numbering scheme used to encode and decode digital messages, is based on an abacus design.
Evolution of Counting Devices
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.
What is the History of an Abacus?
Seki Kowa removed one bead all from upper and lower decks for making the abacus to 1/4 decks. It became popular after globalization when there was intense competition in the world on a common platform. It also influenced the education system of different countries. Furthermore, the abacus improves the overall conception of math, and it also enhances the problem-solving ability and faster calculation skills.
It has also become a symbol of cultural heritage and a reminder of the vital role that ancient mathematical tools have played in shaping the modern world. The Chinese abacus, also known as the suanpan (算盤/算盘, lit. “calculating tray”), comes in various lengths and widths, depending on the operator. There are two beads on each rod in the upper deck and five beads each in the bottom one, to represent numbers in a bi-quinary coded decimal-like system. The suanpan can be reset to the starting position instantly by a quick movement along the horizontal axis to spin all the beads away from the horizontal beam at the center. The beads that are located at the lower of the frame are called “Earthly beads,” and these contain one value in the first column. 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.

The Abacus was so important in ancient times that it was often called the “calculator.” Experienced abacists can perform some calculations faster than an electronic calculator, but it takes a great deal of practice and expertise to reach that level. For most people, the ease and simplicity of using calculators and other devices overshadow the potential gains of learning to make calculations on an abacus.
Who invented the first abacus?
Over it is spread a cloth, bought in Easter term, with a special pattern, black, ruled with lines a foot, or a full span, apart. In the spaces between them are placed the counters, in their ranks. With the Japanese version, only the index finger and thumb are used.
The Schoty is a Russian abacus invented in the 17th century and still used today in some parts. The accountant sits in the middle of his side of the table, so that everybody can see him, and so that his hand can move freely at its work. When the sum demanded of the sheriff has been set out in heaps of counters, the payments made into the Treasury or otherwise are similarly set out in heaps underneath. The lower line is simply subtracted from the upper.” —The Dialogue on the Exchequer, 1177. “The Exchequer is an oblong board measuring about 10 feet by 5…with a rim around it about four finger breadths in height, to prevent anything set on it from falling off.
- It has been a boon for the visually challenged as learning placement value, and other calculations can be done by touch.
- Then, as even larger quantities (greater than ten fingers and toes could represent) were counted, people picked up small, easy-to-carry items such as pebbles, sea shells, and twigs to add up sums.
- Drawings of people using counting boards have been found dating back to the same time period.
- The counting board is a piece of wood, stone or metal with carved grooves or painted lines between which beads, pebbles or metal discs were moved.
- So, the farthest column on the right would be the “ones” place (1-9), the second farthest the “tens” place (10-99), the third farthest the hundreds ( ), and so on.
- The abacus is used in many countries even today and an efficient method to achieve proficiency in arithmetic.
- Many study’s have shown that no one in particular has made the abacus but many believe it was made in China.
- Mesopotamia or Sumerian civilization used the first Abacus to count.
This inexpensive, 13-rod abacus features a red felt backing which prevents beads from slipping during calculations. The device is considered to be a valuable teaching tool for visually impaired students. It can be used to perform addition, subtraction, multiplication, and division. The idea of this counting frame is that each rod represents a sequential place value.
Many designs have four or five beads on a bottom row, with one to five beads on the top row. Pushing one bead from the top row to the center counts as five. You can then push additional beads from the bottom or, if available, from the top to count up to nine in that place value.
Earlier counting devices that were used for counting are the human hands and their fingers that are capable of counting only up to ten. Toes were also used to count when they had to count more than ten. A larger quantity was counted, with the help of natural items like pebbles, seashells and twigs.
An abacus is a mechanical device that is used to calculate the arithmetic calculations quickly, also referred to as a counting frame. Its name was originated from the Latin word ‘abax’ or ‘bacon.’ Originally, it was invented thousands of years ago to perform arithmetic calculations, and today’s is widely used in brain development programs. It comprises a rectangular frame that holds vertically organized rods on which beads move up and down. The main purpose of an abacus is to increase the brainpower of the children.
Careful observers will note that the metal rods, on which the beads slide, have a slight curvature to prevent the “counted” beads from accidently sliding back to the home-position. The design of the schoty is based on a pair of human hands (each row has ten beads, corresponding to ten fingers). Despite the abacus being ancient in its origin, it is still in use today. It has been a boon for the visually challenged as learning placement value, and other calculations can be done by touch. In many countries abacus is taught to early school goers as it has been seen that it helps subtends have a better understanding of numbers.
The two possible binary digits are 0 and 1, but they are also described as low and high, which are the two possible positions for beads on an abacus. This counting frame allows individuals to track, add, subtract, multiply, and divide numbers easily. It helps ensure quick calculations when working with large numbers and makes the calculation process visible to both buyer and seller or teacher abacus market dark web and student. Despite its long history and unknown inventor, the abacus has worked basically the same way throughout the centuries. It’s a fairly straightforward calculator that is still used in many countries in schools or markets for counting. Although most children find maths dealing with numbers difficult, it is to be remembered that enough practice can help one master any skill.
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.
Below these lines is a wide space with a horizontal crack dividing it. Expert abacus users can sometimes do calculations faster than on a calculator, and can even use them to find the square root of whole numbers. As mentioned earlier the thumb and the index fingers play a very prominent role in mastering the abacus. The abacus is used in many countries even today and an efficient method to achieve proficiency in arithmetic.
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.
