¶ XXVII. TO MULTIPLY BY 1, 1, 7, 51, &c 1. How much is of 10?of 18? of 16? of 20

RULE.

Q. To multiply 4 by 2, we take 4, 2 times; to multiply by 1, we take 4, 1 time; and to multiply 4 by, we take 4, a time, that is, the half of 4, and to get this, it is plain that we must divide 4 by 2. From these remarks what appears to be the rule for multiplying by 2, 3, 1,

&c.?

A. Divide the multiplicand by the figure below the line.

Q. How much is of 20 of 20 of 12? of 12? of 12? Q. In these examples, we divide by 5 to get of 20: then it is plain, that is 2 times as much as, that is, we multiply of 20, which is 4, by 2, making 8: but we might multiply 20 by the 2 first, and divide by the 5 afterwards; thus, 2 × 20405, 8 times, the same result as before: how, then, does it appear that we can proceed to multiply by ,,, &c.?

A. Divide the multiplicand by the figure below the line, and multiply this quotient by the figure above the line; or multiply first, and then divide. Exercises for the Slate.
