...two places; by 1000, three places, and so on. Rule : To multiply a decimal by any power of 10, shift the decimal point as many places to the right as there are ciphers in the multiplier, adding ciphers if necessary. Thus : 7-63x100000 = 763000.

...the deficiency by prefixing ciphers. NOTE. — To multiply a decimal by 10, 100, 1000, &c., remove the decimal point as many places to the right as there are ciphers in the multiplier ; and if there be not places enough in the number, annex ciphers. Thus, 1.25 X 10 = 12.5; and 1.7 X 100 = 170. Proof....
