Abacus is a very simple mechanic calculator. It’s been around since ancient times. It is a very helpful tool for merchants and auditors. It is a useful learning piece of equipment for the visually impaired, as well as for anyone who wants to learn the origins of a modern calculator. In this topic, we ‘re talking about abacus, how to use it?
Abacus is a tool that has rods and beads and is used for mathematical calculations such as addition, subtraction, multiplication and division. Just by moving the beads from left to right, you can add up to a billion or more. Although we have technology in which to calculate complex mathematical problems on Go, Abacus trains the mind to calculate without any external technological tools, such as gadgets, mobile devices or calculators. It’s really fun, if you know abacus and how to use it?

The abacus is a square-shaped instrument made of wood, consisting of ten different wires or strings placed in parallel. Each of these strings has ten moving balls. It’s an instrument that helps people make simple calculations.
Abacus, how do you use it today?
Today, it is still heavily used in Africa, Japan, Russia, China and other countries as a visual reference to encourage the learning of mathematical concepts. Children in Asian countries are educated Abacus in their childhood days so that they can concentrate and reduce their fear in numbers. The term abacus is derived from the Greek word “abax,” which means “computer board” or “computer tablet,” according to UCMAS.
If, you want to teach Abacus, and first you have to know. Now we are discussing the steps of the abacus, how to use it?
Step 1 Counting
Align the abacus properly. Each column in the top row must have one or two beads per row, while each column in the bottom row ought to have four beads. When you begin, all beads will be up in the top row and down in the bottom row. The beads in the top row are the number 5 and each bead in the bottom row is number 1.
Allocate a place value to each column. As with a modern calculator, each bead column contains the “place” value from which you build a number. So, the farthest column on the right would be the “one” place (1-9), the second farthest the “tens” place (10-99), the third farthest the hundred (100-999) and so on.
Begin to count the beads in the lower row. Move a bead to the “up” location to count a digit. “One” is to move a single bead in the farthest column from below row to the right to “up,” “two” to pull 2 etc.
Perform the “4/5 swap.” Because there are only four perforations on the bottom row, to move from “four” to “five,” you shift the perforce in the top row down to the “down” position and shift the four perforates from the bottom row down. The abacus correctly interprets as “five” at this place.
Repeat the higher number sequence.
Step 2 For Addition and Subtraction
Please enter your first number. Claim you have 234 and 678 to add. Enter 234 on the abacus by putting four beads in the unit place, three in the 10th and two in the 100th.
Start to add from the bottom. The first numbers that you can add are 2 and 6 from 100, where the single bead travels from the top row of the column down to 6 and leaves a total of 8 on the lower bead. Only, to add 7 in the 10th position, move the top bead from the bottom to 10 in the 10th and one bead.
Complete an exchange. Because the two numbers are added in the tens position to 10, you ‘re going to bring 1-100, turning it into 9 in that column. First, bring all the beads in place, making it empty.
Count your beads for the reply. You are left with a 9 of the ages, a 1 of the tens and a 2 of them:
234 + 678 = 912.
Subtract by reversing the addition process. Borrow numbers from the previous column rather than bring them over.
Step 3 Multiplication
Multiplying the abacus involves a certain degree of focus and counting.
Move the same number of beads as the first multiplication question on the slide. For instance, when you multiply 6 * 4, transfer six beads into the rack. Begin with the beads at the top and shift them to the right from the left to keep your calculations more organized and easier to follow. All beads on the abacus should be put absolutely to the left when the calculation begins to ensure that you are not confused.
Repeat the above step as the second number in the equation. For the example 6 * 4 you ‘d move six beads four times to the opposite side of the rack. Down to the second row of the abacus once the first row is completely moved over and keep moving from left to right after the row above it runs out.
Count the total number of beads that you have passed to get the reply.
A smaller number may be multiplied by similar means by counting one bead as a small number, for example, five or ten. This stops the estimate from running out of beads.
Step 4 Division
Leave the right of the divisor and the dividend space for your answer. If you split on an abacus, you put the splitter into the left column(s). Leave a few blank columns right and place the dividend next to them in the columns. To do the work leading to the answer, the remaining columns to the right are used. Leaving those now blank.
In the left-most column, for example, to divide 34 by 2, let two blank columns and then put 34 on the right. Leave the other columns in the answering section blank.
Record quotient. Record quotient. Split the first dividend number (3) by the divisor (2), and placed it in the comment segment of the first blank column. Two go into three once, so record one there.
Determine the rest. Then, in the first answer column (1) you have to subtract the quotient by the dividend in column one (2) to calculate the balance. After that exclude commodity (2) from the first dividend board.
Repeat process. Repeat process. In the next blank column of the answer, the segment inserts the next digit of the quotient, removing the product from the dividend (excluding it here).
Is abacus helpful to kids?
Let’s get into how an abacus works and how it can be dangerous for the mathematic potential of your baby.
Using abacus is just like playing on a computer keyboard to help you write much easier, but it can’t be easy to type. Understanding abstract equations will ruin your child’s cognitive skills. When you suggest your child will add 15 and 19, she will add them, even though he doesn’t know their real values. Families feel good when seeing the measurement speed of the infant, but at this point, they need to understand that the speed does not matter.
In the lower grades, your child can obtain excellent results when simple mathematical calculations are checked. However, this exam cannot find out the dark side of your child’s mind. Due to the lack of basic understanding of numbers and mathematics, your child may have a phobia to maths.
It would have been too late when you realized it. This impairs a child’s social growth. I say to you because I have carefully and researched its results. My humble request is to make them no robots; to encourage them to think, reason and explore. N0w, the choice is yours.
I have found that Abacus is a positive thing for mankind. Brains are prepared for numbers that support cleverer and smarter. Abacus training in modern times allows our culture to believe in our body’s hard structure. Not only that, abacus how to use have provided fantastic work in education for many around the globe. And parents began focusing on their children’s intellectual strength well before their age. Thank you to all those noble educators who have spent the right resources to make Abacus work
