The abacus is a counting device, but before using one, you must learn how to use an abacus. All of mathematics is about having fun with numbers. Your ability to play with them cleverly will depend on you. An old tool used in mathematics is the abacus. How to use an abacus in Mathematics is covered in this guide.
The traditional construction of an abacus includes a frame that supports wires or rods on which moveable beads are positioned. As computations are made, the beads which represent digits are moved.
For thousands of years, people have used abacuses to count and compute. Who invented the abacus, in the beginning, is a subject of significant debate. There are valid claims that the abacus originated in China, Babylon, Greece, and a number of other nations. Here’s how to use an abacus.
How To Use An Abacus For Counting?
Mathematical operations like addition, subtraction, multiplication, and division are performed on it and counting. An abacus is a fantastic tool for teaching calculator usage to anyone, whether they are high school students or kindergarteners. It is helpful as a counting tool, as the name suggests.
We are aware that your interest in learning how to use an abacus is growing as you read. How to use an abacus is discussed in detail in this article. Let’s get into the details of how to use an abacus.
Orient Your Abacus Correctly
The top row’s columns should have one or two beads per row, while the bottom row’s columns should have four beads per row. When you begin, all the beads should be in the top row and bottom row, respectively. Individually the bead in the bottom row represents the number value 1, while those in the upper row each represent the value 5.
Place Values Should Be Given To Each Column
Every column of beads, like on a contemporary calculator, stands for a “place” value from which you construct a numeral. As a result, the “ones” column (1-9) would be the farthest column on the right, followed by the “tens” column (10-99), the “hundreds” column (100-999), and so on.
Alternatively, if necessary, you might designate specific columns as decimal places.
As an illustration, the first decimal place would be in the farthest right column for a value like 10.5, the ones in the second column, and the tens place in the third column.
Beads in the lower row should be used to begin counting. One bead must be moved to the “up” position in order to count a digit. A single bead from the bottom row in the farthest column to the right would be moved to the “up” position to symbolize “one,” a pair for “two,” and so on.
To move the beads in the bottom row and the top row, you should find it easy to use your thumb and index finger, respectively.
Count Five Or Six On Abacus
Finish off the “4/5 exchange.” The top row bead must be pushed to the “down” position to change the number from “four” to “five,” as there are only four beads on the bottom row. It is correct to read “five” on the abacus in this place. How to use an Abacus to count 6?Push a bead from the bottom row up to indicate the number “six.” The top row bead is down already (meaning a value of 5); when you move a bead from the bottom row up, it will represent count 6.
To Get Higher Numbers, Repeat The Sequence
Practically every abacus uses the same procedure. From “nine,” where all the beads in the one place are pushed up, and the bead in the top row is pushed down, to “ten,” where one bead from the tens place’s bottom row is pushed up (while the beads in the one’s place are pushed back to their starting or “0” position).
As an illustration, for the number 11, the bottom row would have two beads pushed up, one in the second column and the other in the first. Twelve would be arranged in the bottom row, with one in the second column and two in the first.
How To Use An Abacus For Addition?
Let us observe how to use an abacus for addition step by step.
Enter First Digit
Let us say you need to add 1234 with 5678. Push up four beads in the position of the one, three in the tens place, two in the hundreds place, and one in the thousands place to enter the number 1234 on the abacus.
Start Adding From The Left
In this scenario, you would move the single bead from the top row of that column down to add the number 5, leaving the lower bead up for a total of 6, and adding the number 1 and the number 5 from the location of the thousands. Move the top bead in the hundreds position down and one bead from the bottom row up to add 6 in the hundreds place, for a total of 8.
You will carry over a 1 to the hundred places, making it a 9 in that column, as adding the two digits in the tens place will result in 10. Then, leave it at zero by placing all the beads in the area marked in tens.
You will proceed similarly for the one’s column. You will carry the one over to the spot for the tens, making it 1, because eight plus four equals 12. The ones are now replaced by 2, and you are left with.
The solution is found by counting your beads. The remaining numbers are a 6 in the thousands column, a 9 in the hundreds, a 1 in the tens, and a 2 in the ones: 1,234 + 5,678 = 6,912.
How To Use An Abacus For Subtraction?
Instead of carrying over the digits from the previous column, borrow them. Consider that you are taking 867 out of 932. Start subtracting column by column beginning on your left after entering 932 into the abacus.
You will leave one bead in the hundreds place since eight splits by nine equal one.
Because you can not subtract 6 from 3 in the tens place, you must borrow the 1 in the hundreds place (leaving it zero) and subtract 6 from 13 to get at 7, which is what you need (the upper bead up and two lower beads). To subtract 7 from 12 instead of 2, repeat the process in the one place, “borrowing” a bead from the area of the ten to make it 6.
Benefits Of Using An Abacus
It Enhances Attention
In addition to learning how to use an abacus and perform basic mathematical operations, children also learn to block out external distractions. Once kids have mastered using the abacus, they progress to a straightforward visualization approach that enables them to mentally assume the abacus and perform calculations.
