The timeline can be divided into three categories:Įxample: Suan pan or Chinese abacus, Soroban or Japanese abacus, Shoty or Russian abacus. The line is showing the evolution of the Abacus from a counting board to the present-day the abacus. When the Hindu number system introduced zero and also the Arbi number system came into use, the use of the abacus diminished and it became limited to counting the Place value of numbers only. It was widely in use in different countries from the Middle East to Japan, China, Russia as well as Europe. Abacus was the first counting machine.Įarlier it was fingers, stones, or any various kinds of natural material. It was said to be invented from ancient Babylon in between 300 to 500 bc. The word Abacus derived from the Greek word ‘abax’ which means ‘tabular form’. □Ībacus: A brief history from Babylon to Japan ![]() To view them click on the Download button.

Abacus was in use in Europe, China, Russia. So, how can we be expected to use a 66 year old computer?īut what if we tell you that you as well as the entire world still use the first calculator created.Ībacus, an instrument to calculate or count by using sliding counters and rod is indeed the world's first calculator. In this modern era of technology, what was launched yesterday can become outdated today. ![]() Would you still buy it for your daily work? Obviously not. 1.Remember ENIAC, the world's first computer? Obviously. So, this post is all about the different types of abacus and their uses. To understand the abacus, its really important to learn about its beginning and how it reached its current state. ![]() It had gone through series of modifications in different period of time, at different parts of the world leading to what we call ‘School Abacus’ that we use today. Types of AbacusĪbacus is not a new invention, it dates back to 2700–2300 BC in the Mesopotamian period as a form of Sumerian abacus. Practicing 10-15 minutes daily can effectively build your math calculative skills. Numbers are physically constructed and manipulated in Abacus. It is consider one of the best way to develop number sense. Abacus is used all over the world as one of the important measures to develop mental math abilities.įor all of you who still don’t know what we are talking about, Abacus is a manual aid to calculating that consists of beads or disks that can be moved up and down on a series of sticks or strings within a usually wooden frame. It follows an interactive approach to train your mind with maths fundamentals to a whole new level. Abacus is one of the most remarkable innovation in the education industry that the human kind has ever achieved.
