III. DUODECIMAL MULTIPLICATION, Duodecimal Multiplication is a method of multiplying similar to multiplication of decimals, with this difference, that the scale of notation in the former decreases in a twelvefold proportion, whereas in the latter it decreases in a tenfold proportion. RULE. Under the multiplicand write the corresponding_denominations of the multiplier, that is, feet under feet, inches under inches, &c. Multiply each term of the multiplicand, beginning with the lowest denomination, by the feet in the multiplier, and write the several products under the respective terms of the multiplicand from which they arise; observing to carry 1 for every 12 from each lower denomination to the next higher. Then multiply by the inches of the multiplier (if any,) in the same manner, and write the products each one place to the right hand, carrying as before at 12. Next, multiply by the parts, (if any,) writing each product another place to the right; and so on: the sum of the several lines of products is the answer. Note 1. When the number of feet in the multiplicand is great, first multiply by the feet of the multiplier, and then, instead of multiplying by the inches and parts, take such aliquot parts of the multiplicand as they are of a foot. 2. When the number of feet in both factors is great, first multiply the feet of the multiplicand by the feet of the multiplier, then take parts of the multiplicand for the inches, &c. of the multiplier: and for the inches, &c. of the multiplicand, take parts of the feet only of the multiplier.
