For convenience the numbers to be added are arranged so that they stand in a column.

EXPLANATION.-For convenience the numbers to be added are arranged so that units stand under units, and tens under tens, etc. Beginning at the right hand, each column is added separately.

Thus, 5+3+7=15, the sum of the units. 15 units are equal to 1 ten and 5 units. The 5 is written under the column of units, and the 1 is reserved to add with the tens.

1 reserved +6+5+1=13, the sum of the tens. 13 tens are equal to 1 hundred and 3 tens. The 3 is written under the column of tens, and the 1 is reserved to add to the column of hundreds.

1 reserved 3+8+2=14, the sum of the hundreds. 14 hundreds are equal to 1 thousand and 4 hundreds, which are written in thousands' and hundreds' places in the sum.

In adding, name results only. Thus, instead of saying, 5 and 3 are 8 and 7 are 15, say 5, 8, 15.
