ADDITION of MONEY. N. B. Four Farthings is one Penny, Twelve Pence one Shilling, and Twenty Shillings one Pound. In the first Example. The Farthings are 15, which is three Pence three Farthings, put down under the Farthings, and carry three to the Pence place, and the Sum of the Pence is 55, which is 4 Shillings and 7 Pence; place the 7 under the Pence, and carry 4 to the Shillings, and the Sum is 129 Shillings, which is 6 Pounds 9 Shillings; place down the 9, and carry 6 to the Pounds, then proceed as in the last Examples of whole Numbers. Addition is proved by making a fecond Addition of the fame Sums, omitting the top Line; then adding the Sum to the top Line, if it makes the Sum of the whole it is right. N. B. Addition of Time, Weight, Meafure, &c. &c. is performed in the fame Manner, only obferving how many of the inferior makes one of the next, afcending by the Tables after Divifion. SUBTRACTION S the taking a small Number from a large one, and the Number found is called the Remains, the Excefs or the Difference. As from 12 take 4, and there remains 8. N. B. In the first Example, I take 4 from 7, and there remains 3, and fo place it down, and proceed to the End of that Example. But in the fecond Example, I cannot take 8 from 7, fo I borrow 10 and put it to the 7, and it makes 17, then 8 from 17, and there refts 9, which I place down, and carry one that I borrowed to the 7, and it makes 8; then 8 from 2 I cannot, but I borrow 10, and add it to the 2, and it makes 12; then 8 from 12, and there remains 4, which place down; and fo proceed to the End, remembring to carry one to the next Figure when you borrow the 10. If you add the Remains to your least given Number, the Sum will be the greater Number given, which is the Proof. Proof 37 17 11/1/ Remains 99 02:114 : Proof 274 19:03 N. B. What you carry at in Addition, you borrow at in Subtraction. A Gentleman bought an Eftate, valued at 74277. 17 s. 11 d. and his Cafh is only 14987. 18 s. 11 d. 4, how much muft he fend for to his Banker to be enabled to pay for it? Place the Sums thus: Value of the Estate The Cash at home 1. S. d. 7427 17 11 This comes from the Banker 5928: 18:11÷ Proof 7427: 17: II N. B.
