Frequent mention being made in this Treatise of Foreign Coins, now disused in Ireland, the following Table is Note. Since 112 pounds make 1C. weight, hundredweights may be brought into pounds by multiplying them by 112; and contrary wise, pounds may be reduced into hundred-weights by dividing them by 112. Examples. Now it is shewn that any number being added to itself, the sum will be equal to the same number multiplied by 2, and the other figures of 112 being 1, a number is multiplied by 112 when put down four times, viz. under itself units under units; again, units in the second place; and again, units in the third place, and then these numbers collected into one sum. Hence it may be easily conceived how any number of hundreds, quarters and pounds may readily be reduced into pounds by addition only, as follows: Let it be required to reduce 7 C. 3grs. 12. into pounds. 29.
