To know the value of any number of figures: RULE.-1. Numerate from tho right to the left hand, each figure in its proper place, by saying, units, tens, hundreds, &c. as in the Numeration Table. 2. To the simple value of each figure, join the name of its place, beginning at the left hand, and reading to the right. EXAMPLES. Read the following numbers. 365, Three hundred and sixty-five. 5461, Five thousand four hundred and sixty-one. 1234, One thousand two hundred and thirty-four. 54026, Fifty-four thousand and twenty-six. 123461, One hundred and twenty-three thousand four hundred and sixty-one. 4666240, Four millions, six hundred and sixty-six thou sand two hundred and forty. Note. For convenience ir eading large numbers, they may be divided into periods of three figures each, as follows: 987, Nine hundred and eighty-seven. 987 000, Nine hundred and eighty-seven thousand. 987 000 000, Nine hundred and eighty-seven million. 987 654 321, Nine hundred and eighty-seven million, six hundred and fifty-four thousand, three hun. dred and twenty-one. To write numbers. Rule.-Begin on the right hand, write units in the units place, tens in the tens place, hundreds in the hundreds place, and so on, towards the left hand, writing each figure according to its proper value in numeration ; taking care to supply those places of the natural order with ciphers which are omitted in the question, EXAMPLES. Write down in proper figures the following numbers : SIMPLE ADDITION. IS putting together several smaller numbers, of the same denomination, into one larger, equal to the whole or sum total; as 4 dollars and 6 dollars in one sum is 10 dollars. Rule.-Having placed units under units, tens under tens, &c. draw a line underneath, and begin with the units ; after adding up every figure in that column, consider how many tens are contained in their sum ; set down the remainder under the units, and carry so many as you have tens, to the next column of tens; proceed in the same manner through every column or row, and set down the whole amount of the last row.

Excess of 9's. wards, and if it be right, this sum total will be equal to the first: Or cut off the upper line of figures, and find the amount of the rust; then if the amount and upper line, when added, be equal to the total, the work is supposed to be right. 2. There is another method of proof, as follows: Reject or cast out the nines in each row or sum of figures, and set down the re 3 m 8 2 mainders, each directly even with the figures 57 6 6 in its row ; find the sum of these remain- 8 7 5 57 ders ; then if the excess of nines in the sum found as before, is equal to the excess 18 3 0 3 of nines in the suin total, the work is supposed to be right. 15.
