Let’s look at the following example:
52 x 63 = 3,276
We first determine the starting rod location to begin entering our first product. Since the number of multiplicand digits is 2 and the number of multiplier digits is 2, our starting rod is 4 rods to the left of the chosen unit rod. Including our chosen unit rod we count 4 rods to the left and enter the first product by multiplying the 5 of 52 by the 6 of 63, 5×6 = 30. Enter 63 on the abacus on the 4th rod.
