vie. i. is to be written, and the other i, referred in _your Mind to he added to the next Row, i and ; : then lay, I and i makes i, which added to 3 make 5 i this write un- derneath, and there will remain only 1, the firft Figure ot the upper Row of Numbers, which alfo muft be writ under- neath ; and thus you have the whole Sum, viz. 1519' ,
So, to add the Kumbers 87899+1 3A03+88 5+19*0 »nt° ene Sum, write them one under another, fo as all the Units make one Column, the Tens another, the Hundreds a third, and the Places of Thoufands a fourth, and io on.— Then fay, 5 and 3 make 8, and 8+9 make 17 j wrI,6 J underneath, and the 1 add to the next Rank ; faying .and 8 make 9, 9+* make 11, and 1 1+9 make 20 ; and hav- ing writ the ounderneaih, fay again, 2 and 8 make IO, and 10+9 make 19, and 19+4 make «, and 23+8 make 31 ; then, referving 5, write down r as before, and lay again, 5+1 make 4, 4+3 make 7, and ,7+7 make 87899 14, wherefore write 4 underneath ; and laftly, fay I34°3 1+1 make *, and 2+8 make .0, which m the 1920
laft Place write down, and you will have the Sum »»_?

Audition of Numbers of different denominations, for inftance, of Pounds, Shillings, and Pence, is perform d by adding or fumming up each Denomination by it lelf, always beginning with the lowed ; and if after the Addition, there be enough to make one of the next higher Denomination, for inftance, Pence enough to make one or more Shillings ; they muft be added to the Figures of that Denomination, that is, to the Shillings ; only referving the odd remaining Pence to be put down in the Place of Pence.— And the lame Rule is to be obferv'd in Shillings, with regard to Pounds.
For an inftance, 5 Pence and 9 Pence make 14 Pence ; now in 14 there is once 12, or a Shilling, and two re- maining Pence ; the Pence, fet down ; and referve 1 Shil- ling to be added to the next Column, which ; f ^ confilts of Shillings. Then 1 and 8 and 2 ^ Q j p and 5 make 16 : the 6 put down, and carry 6J rJ ? the 1 to the Column of Tens ; 1 and 1 and „ 8 o
1 make three Tens of Shillings, or 30 Shil- r ,
lings; in 30 Shillings there is once 20 Shil- l6 z
lings, or a Pound, and 10 over : write one in the Column of Tens of Shillings, and carry 1 to the Co- lumn of Pounds; and continue the Addition of Pounds, ac- cording to the former Rules.
Addition of 'Decimals, is perform'd after the latne manner as that of Whole Numbers ; as may be feen in the following Example. See alfo Decimal.

Addition of Vulgar Fractions, fee under the Article Fraction. .
Addition, in Algebra, or the Addition of Species, is nerform'd by connecting the Quantities to be added by their proper Signs ; and alfo by uniring into one Sum, thole that can be fo united. See Quantity, Species, &c.
Thus, a and b make a-\-b ; a and — b make a— b ; —a a „a — I make — a— b ; -a and 9a make 7«+9« ; — aV ac and b^/ac make— a^/ac+b^ae, or b^/ ac— a-/ac ; for it is all one in whatever Order they be written.
But, particularly, 1°, Affirmative Quantities of the fame Species or Kind, are united by adding the prefix d Num- bers whereby the Species are multiplied. See Positive.
Thus, Ta+9a make 16a. And nbc-\-i^bc make z6bc. Alfo 5 i+5- make 8 - ; and i^ac+T/ac make 91/ac; 6^ab—xx-\-T/ab—xx make \%t/ ab— xx. And in like manner 6/3+7/3 make 13/3- A g ain > a/ac+b^ac make a+bV<» c i b y adding together a and b, as Numbers mulriplying/rfc. And fo za+^c</jfxx— x' +ja^/^axx— x> a-\-a a-\-x

' 1° Affirmative Fractions, which have the fame Denomi- nator, are added together by adding their Numerators.

, u Negative Quantities are added after the fame manner as Affirmative."*^™^- ^
Thus, -2 and -3 make -5 i — J <""> y make
__—^— - — a^ax and — b>/ax make — a — b\/ax.
When a Negative Quantity is to be added to an affirmative
one ; the Affirmative muft be diminifh'd by a Negative one.

Thus, 3 and — 2 make 1 ; -j— and — ~j make -r-
— a<Jac and b^ac make b — a>/ac.
And note, that when the negative Quantity is greater than the Affirmative, the Aggregate or Sum will be Nega-

tive. Thus, 2 and — 3 make — 13 — ~J~ and -j- make
lax — —7- ; and 2</ac and — f/ac make — 5/flC.
Addition of Irrational Quantities. — If they be of dif- ferent Denominations, reduce 'em to the fame Denomina- tion ; and if they be then commenfurable, add the Ratio- nal Quantities without the Vinculum ; and to their Sum pre- fix the Radical Sign.— The reft as in the Addition of Ra- tional.
Thus, we lhallfind 1 /8+/i8=2/+3 /2=5/2=5o. On the contrary, / 7 and / 5 being incommenfurable, their Sum will be •/7+V / 5-
Addition, in Law, is that Name, or Title which is given to a Man, over and above his proper Name and Sir- name ; to fliew of what Eftate, Degree, or Myftery he is ; and of what Town, Village, or Country.
