There is likewise another kind of Addition, that is not of whole Quantities, wherein is necessary to be known the number of Parts the Integer or whole Number is divided into, as Pounds and Shillings, every Pound is di∣vided into 20 Shillings, and one Shilling is divided into twelve Pence, one Penny into four Farthings.
Now being to add a Number of Pounds and Shillings together, they are thus set down with a small Line or Point between them.
〈 math 〉〈 math 〉If these be added together, observe in casting up your Shillings, so many times as you have 20 in the Shillings, you must carry Unites to the Pounds, and set down the Remainder, being under 20, as in these Examples.
〈 math 〉〈 math 〉In the first Example, I find in adding the Shillings together, they make 21, so I set down 1 and carry 1 Pound to the Pounds: In the second Example, I find among the Shillings 53, which is 2 Pounds 13 Shillings, so I set down 13 under the Shillings, and 2 to the Pounds.

Any number of Shillings and Pence being to be added together, if your number of Pence amount to above 12, carry 1 to the Shillings, and set down the remainder under the Pence; if they make above 24, carry 2 Shillings, and set down the remainder, as before.
Examples.
〈 math 〉〈 math 〉In the first Example, you carry one Shilling; in the second, two; and in the third, three.
In Addition of Pence and Farthings, carry so many times four as you find in the number of Farthings to the Pence, setting down the remainder under the Farthings, as in these Examples.

When you would know the Sum of any number of Pounds, Shillings, Pence, and Far∣thing, they are to be placed thus:
〈 math 〉〈 math 〉Addition of Weight and Measure is perfor∣med after the same manner.
- 16 Ounces Averdupois, make a Pound.
- 28 Pounds, make a Quarter.
- 112 Pound, or 4 Quarters, make an Hun∣dred gross.
- 20 Hundred, make a Tun.
Examples.
〈 math 〉〈 math 〉Where observe, that so oft as I find 16 Oun∣ces, I carry 1 to the Pounds; so often as I find 28 Pounds, I carry 1 to the Quarters; and as many times as I find 4 in the Quarters, so many times 1 do I carry to the Hundreds.
