We then add tne units thus--3 and 1 are four, and 2 6 3 12 are sixi ar,d are eight; and we write 8 8 0 32 under the column of units. We next add 5 0 1 the column of tens, and, finding their sura 7 12 3 to be 6, we write 6 under the column. In. the same manner we add the hundreds, and 21 the thousands. Find the sum of the numbers in each of the following examples, by addition upon the slate. (2). 51 (3). 733 (4). 6243 (5). 24031 4 120 4123 1320 60 12 9401 40214 43 634 130 34314 Section 2. 1. Add the following numbers into one sum. 4638 and 216 and 8329 and 1212. » Finding the sum of the units to be 25, or g"! 2 tens and 5 units, we write only the 5 units, ga and presently add the 2 tens in with the column of tens.

Now if we 216 should write down 13, the 3 would stand 8 3 29 under the column of hundreds, and the 1, 1212 under the column of thousands; therefore l 4 3 g g we write the 3 only, and presently add the 1 in with the thousands. In the following examples, observe, that when the sum of any column amounts to more than 9, you must set down only the right hand figure of it, and, must add the left hand figure to the next column.
