A RITHMETIC is the art of computing by numbers, and has five principal rules for its operation, viz. Numeration, Addition, Subtraction, Multiplication, and Divi Nomeration is the art of numbering. It teaches to foress the value of any proposed number by the following characters, or figures: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0–6, cypher. Yesides the simple value of figures, each has a local waite, which depends upon the place it stands in, viz. toy figure in the place of units, represents only its sim;3 value, or so many ones, but in the second place, or Note.—Although a cypher standing alone signifies nothing; yet when it is placed on the right hand of figures, it increases their value in a tenfold proportion, by throwing them into higher places. Thus 2 with a cypher annexed to it, becomes 20, twenty, and with two cyphers, thus, 200, two itindred, 3. When numbers consisting of many figures, are given to 'o read, it will be found convenient to divide them into as gally periods as we can, of six figures each, reckoning from file right hand towards the left, calling the first the period of fits, the second that of millions, the third billions, the fourth sińczs, &c. as in the following number: § {} 7 3 to 2 5 4 6 2 7 & 9 0 1 2 5 0 6 7 9 2 ', he foregoing number is read thus—Eight thousand and Sooty-three trillions; six hundred and twenty-five thouand, for hundred and sixty-two billions; seven hundred and ine thousand and twelve millions; five hundred and and, seven hundred and ninety-two. N. B. Billions is substitute i for millions of millions. 'i' ilions for millions of millions ef millions. Quatrillions for millions of mills us of millions of millions, te. |
