The compleat arithmetician, or, The whole art of arithmetick, vulgar and decimal in a plain and easie method, suitable to the meanest capacity : in which the multiplication and division of numbers of several denominations, and the rule of alligation are more fully explained than in any treatise of this nature, yet extant / by J.N., Philomath.

The use of the Table.

THis Table doth consist of six Columns, in the first, you have each other Grain in two penny weight Troy, in the second every penny in two shillings, in the other four Columns you have the decimals, answering to the grains in Troy weight, and to the pence and farthings not exceeding two shillings in En∣glish mony. Example, let the decimal 1 penny weight, and 16 grains, be required, or the deci∣mal of 40 grains, I look for 40 grains in the first Column, and in the third, I find the decimal thereof to be 083333. Or let the decimal of 1 penny weight, and 11 grains be required, that is the decimal of 35 grains; 34 grains I find in the Table; and therefore in the same line in the first Column, I find 072916, for the decimal there∣of▪ if the decimal of 17 penny weight and 13 grains were required, the decimal of 16 penny weight is the half thereof; viz. 8 and that decimal of one penny weight 13 grains is 077083 and so the decimal required, is 8.077083, the like may be done for any other; and so for mony you have the pence in the second Column and the farthings in the top of that page, and in the angle of meeting the decimal answering thereunto, thus the decimal of 19 pence 3 farthings is 08••291 and so for any other.
