* The reason of this rule is cvitent from what has been said in addition of simple aumbers: for, in addition o. money, as 1 in the pence is equal to 4 in the farthings; 1 in the shillings, to 12 in the perice; and 1 in the pounds, to 20 in the shillings;-therefore, carrying as directed, is ananging the money arising from each colunin, properly, in the scale of der olluati as: and is reasoning will hold good in the addition of com pound numbers of to dewwow nation whatever.

In this example, we begin by placing the numbers of one denomination under each other, that is to say,-pounds under pounds, shillings under shillings, and pence under pence. We then begin with the least denomination, which is pence, and find the amount to be 46, which we bring into shillings by dividing them by 12,-we write the remainder 10 under the column, and carry the quotient 3 to the column of shillings; we then find the amount of the column of shillings to be 93, which we bring into pounds by dividing them by 20; we write the remainder 13 under the column of shillings, and carry the quotient 4 to the pounds;--we then find the amount of the column of pounds to be 174, which we write under the column of pounds, and find the answer to be 174£. 13s. 10d.

* The original of all weights used in England, was a grain or kernel of wheat, gathered out of the middle of the ear, and, being well dried, 32 of them were to make one pennyweight, 20 pennyweights one ounce, and 12 ounces one pound. But in later times it was thought sufficient to divide the same pennyweight into 24 equal parts, still called graius, being the least weight now in common use; and from thence the rest are computed.
