ADDITION OF DIFFERENT DENOMINATIONS.

[ocr errors]

When it is required to add together several numbers of different denominations, such as pounds, ounces, &c., for the purpose of finding the sum, or amount total, it has generally been designated as Compound Addition; or, by some, Denominate Numbers, which signifies" to name,” and Denomination, which signifies a name given to a thing, title, &c., either of which may be correct, as it is unimportant what the title is, provided the subject is understood, although we have given the last-mentioned 'the preference. The Cwt. avoirdupois (112lbs.) has been in use many years, but is not so much used of late, as the merchants in the principal cities have substituted the 100lbs. net weight for the 112lbs. avoirdupois. This change will be attended with many advantages, it being by far the most agreeable and expeditious method of computation, as it could easily be reduced to a system of decimal calculations, and the division of the 100lbs. into 10ths; and this system should extend to LENGTH, and our weight, measure, &c., would correspond with our currency, which may, and probably will, some day not far distant, be the case.

RULE.

1. Write down the numbers so that each denomination may stand directly under each other, leaving a small space between them.

2. Add the right-hand denomination, the same as in Simple Addition.

3. Then divide that amount by as many as it requires of that denomination to make one in the next.

4. Set down the remainder under that denomination, and carry the quotient to the next denomination, and add it in; if there be no remainder, set down a cipher.

5. Continue in this way through to the last denomination, which add, the same as in simple addition, and set down the whole amount. Proof': the same as in whole numbers.

EXAMPLES,

10 20. 4. 28. 16. 16. Explanation. This example bec T. cwt. qrs. Ibs. oz. dr. longs to avoirdupois weight, but the 2 3 2 11 6 8 same general rule will hold good in 4 1 3 16 11 12 all cases of compound numbers. The 2 4 0 18 10 14 first denomination at the right hand

is drams, which add, the same as in 8 9 2 18 13 2 simple addition, and the amount is

34; this is divided by 16, because 16 drams make 1 oz., and we have 2 ounces in the quotient, and 2 drs. over ; set down the 2 drs. and carry the 2 oz. to the de nomination of that name, which add in, and it will make 29 oz. ; divide the 29 oz. by 16, to get the pounds, and it will give 1 lb. and 13 oz. over ; set down the 13 oz., and carry the 1 lb, to the next denomination ; then add that denomination, and it will give 46 lbs.; divide the lbs. by 28, to bring them to quarters, and you have 1 qr..and 18 lbs. ; set down the 18 lbs., and

carry

the 1 qr. to the denomination of that name, which add in, and you have 6 qrs., which divide by 4, because 4 qrs. make 1 cwt., and you have 1 cwt. and 2 qrs. ; set down the 2 qrs.,

the 1 cwt. to the next denomination, and add it in; you will then have 9 cwt., there being none to carry now, because it is less than a ton; then add and set down all of the next denomination, you have the sum total. 1. lbs. oz.
