h) The highest digit of the multiplier and the lowest digit of the multiplicand
should be multiplied first.
i) When multiplication of one digit with the multiplier is over, the completed digit
of the multiplicand should be immediately cleared before taking up the next
digit of the multiplicand for multiplication. The multiplied value will always
appear in the right side of the multiplicand.
j) When the placement of the multiplicand is correct, the digits of the product will
appear in their respective places.
II. MULTIPLICATION
A) Multiplication of Single Digit Numbers :
Example : 4 x 7
a) The multiplier 4 is placed in the left extreme of the abacus.
b) Move both hands to the extreme right to find out where should we place the
multiplicand.
c) For that, count the number of digits in the multiplier and multiplicand and add
one column or digit for the abacus.
d) In this example, there is only one digit in the multiplier and one digit in the
multiplicand and add one for abacus. The total is 3 (places).
e) From the extreme right, count 3 places: - first column-units, second column -
tens and the third - hundreds. Therefore, we have to place the multiplicand 7 in
the hundreds column with right hand.
f) Multiply the multiplier and the multiplicand. That is, 4 x 7 = 28. Set the number
2 of the 28 in the tens column and the number 8 of the 28 in the units column.
g) Clear the multiplicand and the multiplier. The number left in the extreme right
of the abacus is the “PRODUCT”. The answer is 28.
