How do you do 2 digit division in abacus?
First we subtract the 6 from 7 on the 3rd rod of the dividend. Next we subtract the 3 from 2 on the 2nd rod of the dividend by first subtracting 1 from 1 on the 3rd rod and adding 7, the 10 pair of 3, to 2 on the 2nd rod leaving 95 on the dividend. Next we compare the first divisor digit 1 to 9 on the soroban.
How do you multiply and divide on abacus?
Performing multiplication on the abacus involves only the addition of partial products. Our first step is multiplying 6 by 4 and adding the partial product on the two rods, GH, to the right of the multiplicand. Since we’ve accounted for the 6, we reset rod F to zero. A similar process is followed to multiply 30 by 4.

Is abacus used for multiplication and division?
What is an Abacus? An abacus is a calculation tool used by sliding counters along rods or grooves, used to perform mathematical functions. In addition to calculating the basic functions of addition, subtraction, multiplication and division, the abacus can calculate roots up to the cubic degree.

Where is the divisor 7 on the abacus?
The divisor 7 is placed on the far left on the abacus. This is how we set division problems on the counting tool. First, the number 7 doesn’t go into the number 3, unless we are dealing with decimals, which is beyond the scope of this article. Therefore, we move over to include the zero in 308.
Which is the opposite function of multiplication on an abacus?
Realizing division is the opposite function of multiplication is essential when working with an abacus. Fundamentally, division is subtraction done repeatedly. When performing division, we must think of the abacus as being split into two sections which helps in understanding these concepts.
