The Abacus: A Brief History

what is an abacus

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.

THE Salamis Tablet

Starting either with the tens place or a decimal place, increasing from right to left. The standard abacus is used to perform basic mathematical application addition, subtraction, division and multiplication. It can also be used to calculate square-roots and cubic roots of numbers. We have to manipulate beads either using the index finger or the thumb of one hand. Affluent merchants could afford small wooden tables having raised borders that were filled with sand (usually coloured blue or green).

  • The abacus is one of many counting devices invented to help count large numbers.
  • When the left hand is used, the cells on the right side of the brain are activated.
  • You can then push additional beads from the bottom or, if available, from the top to count up to nine in that place value.
  • In the bead frame shown, the gap between the 5th and 6th wire, corresponding to the color change between the 5th and the 6th bead on each wire, suggests the latter use.
  • The abacus is a device, usually of wood (romans made them out of metal and they are made of plastic in modern times), having a frame that holds rods with freely-sliding beads mounted on them.
  • The Chinese Abacus, or the suanpan, is the most widely used and recognizable type of Abacus.
  • A piece of soft fabric or rubber is placed behind the beads so that they do not move inadvertently.
  • Despite its long history and unknown inventor, the abacus has worked basically the same way throughout the centuries.
  • With technological progress came mechanical calculators and, eventually, electronic computers that built upon its principles.

Chinese Abacus

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.

Who Used the First Abacus to Count?

It was used in 300 BC by the Babylonians and was discovered in the year 1849 on the island of Salamis. Around the 11 century, the invention of money added a new dimension to trade. Merchants who previously traded goods and just kept track of inventory now needed to calculate the cost of those goods and currency conversion calculations were required if the trade was with a different culture. Based on the ten fingers of a pair of hands, the numbers on the right indicated the multipliers for the beads in the corresponding row. 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.

Abacus Life Inc Stock Price History

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.

The Abacus: A Brief History

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.

More Powerful than a Calculator

Abacus, a counting frame, is a primitive yet innovative tool used for arithmetic calculations. Its origin can be traced back to ancient civilizations such as Egypt, China, and Greece. An abacus typically comprises a wooden or metal frame with rows of beads or stones that slide along rods or wires. The position of the beads denotes their value, and this arrangement aids in performing simple to complex arithmetic operations.

The groove marked I indicates units, X tens, and so on up to millions. The beads in the shorter grooves denote fives (five units, five tens, etc.) resembling a bi-quinary coded decimal system related to the Roman numerals. The short grooves on the right may have been used for marking Roman “ounces” (i.e. fractions).

Renaissance abacuses

In austere field environments, rudimentary abaci have been commonly used by infantry soldiers among many of the worlds’ armed forces up to the present day. Another popular use of abaci around the world is to teach arithmetic to children, especially multiplication; the abacus can substitute for rote memorization of multiplication tables. So in many Asian countries, the abacus remains a point of cultural pride and mathematical skill. So while the exact origin is uncertain, abacuses developed across Eurasia over thousands of years as an efficient calculation tool.

Is an Abacus Faster Than a Calculator?

Removes the fear of mathematics by making arithmetic calculations easier. It is also said to improve one’s concentration, Listening Skills, Memory, Speed, and accuracy, among other things. “One” would be represented by pushing a single bead from the bottom row in the farthest column on the right to the “up” position, “two” by pushing two, etc. First, make sure each column in the top row has one or two beads per row and each column in the bottom row has four. While starting, all of the beads should be up in the top row, and down in the bottom row.

what is an abacus

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.

An abacus is a manual calculator that uses sliding beads to represent numbers. The rows and columns of beads represent the digits in your number. Talking of the structure of the Abacus, it has one upper and four lower beads in one rod. Abacus has 17 rods in a standard Student Abacus or teacher Abacus. The divider is used to separate the left and right strings of beads. It has a total of seven beads, out of which two beads on the rods on one side and 5 beads on the rods on the other side of the divider.

As written calculations became easier, the abacus passed out of use in Europe. But it continues to be used by people living in China, Japan, and the Middle East. As commercial transactions became more complicated, a calculating tool was essential to make quick calculations and avoid errors. This origin, whether in Ancient China or Babylon, has been used throughout history and is continued to be used as a convenient calculator for commercial transactions. The abacus is also an excellent tool for teaching other base numbering systems since it easily adapts itself to any base.

  • Using the Abacus helped early civilizations advance in trade, architecture, and engineering.
  • It is an instrument that is used to calculate or count by using sliding counters and a rod.
  • 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 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.

Counting

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.

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.

Which Country used the Abacus first?

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 earliest counting boards are forever lost because they were constructed of perishable materials like wood.

  • In the 1st century AD, there were some advancements in the Roman Abacus like the addition of eight long grooves consisting of up to five beads and eight shorter grooves having no or one bead each.
  • These days people rely on calculators on their computers and cell phones.
  • It is important to distinguish the early abacuses (or abaci) known as counting boards from the modern abaci.
  • 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.
  • In addition to calculating the basic functions of addition, subtraction, multiplication and division, the abacus can calculate roots up to the cubic degree.

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.

It is however to be kept in mind that the student should be well learnt with numbers upto 100 before they start learning Abacus. The introduction to the Abacus at a very young age will help the students immensely in understanding the basics of numbers, which will in effect play a very major role in their higher education. It also develops the creative and imaginative abilities of the students. Mesopotamia or Sumerian civilization used the first Abacus to count. It is the belief that Old Babylonian scholars have used this Abacus to perform as addition or subtraction of numbers. Today we find the oldest surviving counting board to be the Salamis Tablet.

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 abacus market onion link 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.

Chinese Abacuses are designed to be used for hexadecimal computation. It can be used for doing division, multiplication and for taking square roots and cube roots as well if the user knows the techniques. We cannot imagine counting without numbers, but there was a time when written numbers did not exist.

With a Chinese abacus, the thumb and the index finger together with the middle finger are used to manipulate the beads. Drawings of people using counting boards have been found dating back to the same time period. Here, at Genie Academy, we’ve understood all that the powerful abacus can offer to your child, both as a calculator and as a tool for increased brain development, even in the twenty-first century. As students use the abacus regularly, their ability to mentally calculate large number operations greatly improves, both in terms of speed and accuracy!

The beads in the top row represent the number value 5 and each bead in the bottom row represents the number value 1. There is evidence that people were using abacuses in ancient Rome (753 b.c.e.–476, c.e.). It is the most primitive form of a calculating device, invented somewhere between 300 and 500 B.C. As one can imagine, how difficult it would be to count without numbers.

  • It was used in 300 BC by the Babylonians and was discovered in the year 1849 on the island of Salamis.
  • The abacus is still taught in Asian schools, and a few schools in the West.
  • Set your first number in the abacus and minus from that number going left to right.
  • 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.
  • The Japanese abacus is called the Soroban which was not used widely until the seventeenth century.
  • A horizontal beam separates the structure into two sections, known as the upper deck and the lower deck.
  • This is known to be the modification of the current Abacus to support the learners that have vision disabilities.
  • Later, the soroban was introduced at the end of the 19th century on which each rod included one five-unit counter and four one-unit counters.

Before the Hindu-Arabic number system was invented in India in the 6th or 7th century and introduced to Europe in the 12th century, people counted with their fingers, and even their toes in tropical cultures. 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. The earliest “abacus” likely was a board or slab on which a Babylonian spread sand in order to trace letters for general writing purposes. The word abacus is probably derived, through its Greek form abakos, from a Semitic word such as the Hebrew ibeq (“to wipe the dust”; noun abaq, “dust”). As the abacus came to be used solely for counting and computing, its form was changed and improved. The sand (“dust”) surface is thought to have evolved into the board marked with lines and equipped with counters whose positions indicated numerical values—i.e., ones, tens, hundreds, and so on.

Before the invention of Computers, calculators, or even arithmetic using paper and pencil, the Abacus was mostly used for counting numbers. Before the invention of the Abacus, the only methods people used were their fingers and toes for mathematical calculations. In this article, we will discuss the Abacus meaning their application and Abacus for kids. In summary it can be concluded that abacus, not only is a great device for calculation but also a great tool for mind development and focus in children. It is great to see such great calculations being solved efficiently using a tool. The recognition of abacus in various countries has been commendable and motivating due to which many organizations have been opened to educate the people about abacus.

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 wooden boards then gave way to even more more durable materials like marble and metal (bronze) used with stone or metal markers. Abaci evolved into electro-mechanical calculators, pocket slide-rules, electronic calculators and now abstract representations of calculators or simulations on smartphones. The abacus has been around for thousands of years, and is still used in some parts of the world. Sometimes blind people will use an abacus, because they can feel the numbers easily. But it also has traces of being used during ancient times near east, China, Japan, and Europe.

In this article, we will discuss what is an abacus, the basic information like who invented it, what is the history of the abacus, what are its different types, and what works have been performed in this field. We will also look into some of the uses and achievements of Abacus. Later, the soroban was introduced at the end of the 19th century on which each rod included one five-unit counter and four one-unit counters. The functionality of the soroban operation was mentioned in arithmetic compiled books of national grade-school by the Education Ministry in 1938. In about 700 ce, the Hindus invented a numeral system that made adding with written numbers as easy as adding on an abacus. The Arabs soon adopted this system, and they introduced it into Europe more than 1,000 years ago.
