This is the part which we will apply for all kinds of numbers. Next, you will multiply 4 with 1 and then 4 with 2. Step 2 - Multiply 3 with 1 and then 3 with 2. Remember, “X” and “=” will be represented by blank columns. Leave the rest of the columns to the right as it is for the answer. Step 1 - Assign one letter into each column. For example, if you're multiplying 34×12.In those cases, we will follow a different approach. There may be situations wherein the student confronts large numbers. Well, but the above-mentioned strategy can only be utilized in case of numbers that are small. Finally, they will have to add 20+4 = 24. Then follow the strategy of five, as mentioned above. All they have to do is enter 6 in four different wires. In order to multiply small numbers, for example, 6×4, we can ask the students to follow the process of addition.Now let's move on to the most important basic mathematical operation which is multiplication. Therefore, it requires patience and regular training. So our final answer will be 932 - 867 = 65.Ī regular practice will make things easier to perform. Now subtract 7 from 12 so you will obtain 5. Because you cannot subtract 7 from 2 you have to borrow 1 from the tens place, which will convert 7 present in the tens place into 6. Now you have to subtract 6 from 13 making it 7. You can't subtract 6 from 3, so you will have to borrow 1 in the hundreds place leaving it with 0. If you subtract 8 from 9 you will receive 1, so you will leave a single bead in the hundreds place. For example, if you want to subtract 867 from 932.Īfter entering 932 in the abacus, start subtracting column by column from the left. All you need to do is borrow the digits from the previous column instead of carrying them over. Subtraction is just the reverse process of addition.
Abacus row how to#
The next operation which you will learn is, how to use an abacus in a step-by-step method to perform subtraction? So, the actual result will be 154.įor more information, check out Abacus Addition. Keep the digit 4 and pass on 1 to 8, thereby making it 9. Start with the first wire and add 5 to 9. The first wire from the right will have 9 and the second wire will have 8. Students will have to represent 89 on an abacus. This strategy works in problems where the two numbers being added are more than five. The two 5s will make it 10, and we will remain with three beads. Once your child masters this strategy on an abacus, you can make them try doing it mentally.įor example, if we have to add 6+7, we will enter 6 and 7 in the first two wires. Then moved from 6 to 9 so that 9 becomes 10 and 6 becomes 5. There are various strategies that can be applied while learning addition.įor example, if we have to add 9+6, we will enter 6 and 9 in the first two columns. Once you have learned how to count Beats 1 abacus, the first operation that we can learn in addition.
The right-most column represents the units column the next adjacent column to the left is the tens column, and so on. 10) is then carried to the left-most adjacent column.
📥īest Way to Use an Abacus for Basic Math OperationsĮach bead in the lower row, as stated, is of value 1.Īfter 5 lower beads are counted, the result is "carried" to the upper row.Īfter both the upper beads in the upper row are counted, the result (i.e.
Abacus row pdf#
If you ever want to read it again as many times as you want, here is a downloadable PDF to explore more. A traditional abacus consists of 13 wires in order to represent very large numbers. Chinese abacuses are designed to allow for hexadecimal computation. The two beads in the upper row have a value of five, and the five beads in the lower row have a value of one each.
Abacus row series#
There is a series of vertical wires to which 7 beads are attached (two in the upper row and five in the lower row) which extends from top to bottom of the frame. It is a simple calculating device that consists of a rectangular wooden frame divided by a horizontal bar into the upper and lower sections. If you are thinking they always used to carry a pen and paper, then you are mistaken.įor centuries, people in Asia have used the Chinese calculator “suanpan,” also known as an abacus. Have you ever wondered how people used to solve mathematical problems before the invention of a calculator or the computer?
