How to use of Abacus
Abacus is the most powerful and interesting invention in the sphere of mathematics. It is nothing but a counting frame that helps an individual to perform mathematical operations like additions, subtractions. But in earlier model of abacus is not that much easy to manage to do multiplications and divisions.
The origin of the word abacus is Latin and we found that abacus was being used in primevalcivilizations. The meaning of abacus is tray of sand in Arabic language. It is used to calculate numbers easily. The advanced abacus is made in Japan and you can perform all the major mathematical operations with the aid of abacus.
Abacus and arithmetical problems especially mental math is interrelated since the day it is being developed. Previously the abacus was made of clay or wood and a flat layer of sand is spread over the tray. The figures were drawn with sticks and there were no beads at all. After calculating one problem you need to spread additional layer of sands in order to calculate further. In 2300 BC Sumerian people firstly used the abacus as numerical tool.
After that in Egypt, Rome, China the abacus is used in order to learn calculations. Now you may find the abacus of white marble slab of the breadth 4.5 cm, the length 149cm and a width of 75cm kept in the national museum of Epigraphy of Athens for the visitors. Chinese abacus is quite user-friendly for the kids learning the basics of math.
Tips to How to use abacus
Now you may have one question in your mind that how to use the abacus and sharpen math skills at very young age. In some Asian schools still abacus is used to demonstrate the numerical solutions in easy manner for kids. At first you have to propagate with the abacus which has several arrangements with ten columns of beads divided by a crossbar.
You have got tomanipulate the beads beside the bar that will define the numbers you are computing. The five beads under the crossbar put up with one unit each, but the two beads above the crossbar symbolize five units each. Now you have to recognize that each column has decimal points related to it. The leading right column signifies for one decimal point and then 0 decimal points and so forth.
Now you have to fix the abacus to the starting point by relocating the beads away from the bar. If there is any bead near the bar that signifies the abacus still has some value. Now you can perform any operation like subtraction by manipulating the beads as per your calculation so that it can exhibit the result of the problem. You can get to know about the numerical value by observing the location of beads on the abacus.
You should control the counters on the abacus by your thumb and index fingers. You may apply your thumb to exchange the beads upward and index finger to deduct the beads. But the electronic devices like calculator is more effective than abacus to perform big calculations and other operations like cubic root or square-root and it would be aiding as it gives you more accurate results than abacus.
