Page 66. Observe that in the first example, 1 is a factor of each product; hence the product is the same as the other factor.

In the second example, one of the factors is one-tenth, consequently the product is one-tenth of the other factor; that is, consists of the same figures, with one additional decimal figure, and this another zero placed before the product of the first examples.

REM.—The division may be carried as far as necessary by an nexing zeros to the dividend, as every additional decimal in the dividend will give an additional one in the quotient.
