multiplicand

To multiply by 10, all you have to do is to put a cipher after the multiplicand.

In arithmetic operations it holds the addend, subtrahend, multiplicand, or divisor.

Therefore zeros in the multiplier would cause a corresponding change of position in the figures of the multiplicand.

It is only fair to admit, however, that the original multiplicand had been rather small.

Then the product has meaning: it is a concrete quantity of the same denomination as the multiplicand.
