The use of Abacus is in several forms like Addition, Subtraction, Division and Multiplication. Here, we have discussed all methods briefly.
Once we know how to count beats 1 Abacus, then the 1st operation to perform is the Addition. Several strategies are applied to learn Addition like:
If we add 3+9, we will enter 3 and 9 in the 1st two columns. Accordingly, we move from 3 to 9 so that 9 will be 10 and 3 will be 2.
We will take two numbers, say, 5+8; then we enter both in the 1st two wires. The two 4s will make it 8, and we'll remain with five now if we perform 8+5 = 13.
Subtraction is the reverse process of Addition. So, we need to borrow the digits from the previous column rather than carry it over.
If you enter 434 in the Abacus, you must subtract the column by column from the left side. So, for example, if you remove seven from 8, you will receive 1, you will leave with a single bead in the 100th place. Accordingly, it would help if you move to the tens place.
If you consistently practice, you will find the use of abacus easy. It is training for every kid.
For example, to multiply small numbers, for instance, 3×7, we ask the students to perform the Addition's process to multiply small numbers. All they have to do is enter 3 of 7 different wires.
Some steps mentioned above will help to perform the basic operations. Plus, you can use this tool to perform high-level calculations and functions.
