P R E F A C E.
Great many have wrote upon this Subject, and most have met with deserved Success ; but how
far this may merit the same, Time alone must determine. I only wish it may meet with impartial, Judges, who will undoubtedly give it a Character equal to its Deserts, and then I bave Reason to believe it will answer the End designed ; that is, to be a Guide to them that want to attain a Knowledge of those useful and entertaining Studies, and an agreeable Companion for such as have made fome Progress in them. The fundamental Rules of Arithmetic are laid down fo plain, that the meanest Capacity, with a little Application, may understand them, and when I come to the Rule of Three, I make use of a few Charakters which the Reader may soon be Master of į and then may proceed with Pleasure. What Rules are omitted, bave their Dependence on the Rules of Proportion, which are fully explained; and as most Questions in PraEtice are done with much Ease and Certainty, by the Multiplication here made use of ; I hope the Want of tbem will be no Defect. I have very plainly and intelligibly delivered the Algebraical Part, and exemplified the Rules with a Collection of Questions, answered in a plain and familiar Manner. I have not notified in the Margin when you are to makeUse of a Step, or an absolute Number ; but the Step following will determine which it is.
I have taken Care to keep this Treatise as free as possible from the Errors of the Press; but if there should be any, I hope the Reader will correal and excuse them. The Questions are mostly answered numerically, being the most easy way to initiate the Use of Algebra to Learners, which when understood, they may use the literal Way with Pleasure.
Eaches to place, or give the juft Value,
to any Number demanded ; to do which, observe the following Table.
The T A BL E,
5 4 3 2 1 Millions.
T. of Mi.
5 4 3 2 1 C. of M.
8 7 6.
9 8 7 6 5 4 3 2 1
In the Table above you see how each Place exceeds the former ten times, increasing towards the left Hand. The first is the Place of Units, the second of Tens, the third of Hundreds, &c.
A D D IT ION Is the gathering several Numbers into one, which is then called the Sum or the Aggregate ; as 6 and
8 are 14.
Addition begins at the right Hand, and adds the particular Sums of the several Rows underneath every one in its own Place.
2 3 7 4
8 7 3 1
6 4 2 5 6 7 3 2 7 2 I 4 7 4 3 I 5 4 7 5 3 74 6
5 7 6 2
In the first Example, the Sum of the first Row is 26; 1 place down the 6 under itself, and carry 2, being the Number of the Tens to the next Row, and find the Sum of it to be twenty, then I place down a Cypher, and carry two to the next Row, and find the Sum to be 31. I place down the 1, and carry 3 to the last Row, and the Sum is 30, which I place down, and it is done. And fo of the rest.
