43. Only numbers of the same kind can be subtracted from each other; thus, we can take 5 books from 8 books; but we cannot take 5 books from 8 marbles.

44. Subtraction is the process of finding the difference between two numbers of the same kind.

45. The greater number is called the Minuend; the less number is called the Subtrahend; and the result is called the Difference or Remainder.

46. The sign of subtraction, -, called minus, signifies

that the number after it is to be taken from the number before it; thus, 743, that is, seven minus four, or seven diminished by four, equals three.

22. From 796 take 582.

Minuend,
796
Subtrahend, 582
Remainder, 214

Write units under units, tens under tens, etc., as in addition. Then 2 units from 6 units leave 4 units, which we write under the units' column; 8 tens from 9 tens leave 1 ten, which we write under the tens' column; 5 hundreds from 7 hundreds leave 2 hundreds, which we write under the hundreds' column. The remainder then is 2 hun

34. From 483 take 257.

Minuend, 483
Subtrahend, 257

Remainder,

226

As we cannot take 7 units from 3 units, one of the 8 tens is put with the 3 units, making 13 units, and then, 7 units from 13 units leave 6 units. Now as one of the 8

tens has been put with the 3 units, only 7

tens remain in the minuend, and 5 tens from 7 tens leave 2 tens, and, finally, 2 hundreds from 4 hundreds leave 2 hundreds; hence, the entire remainder is 2 hundreds, 2 tens, 6 units, or 226.

35. From 256.17 take 187.245.

256.17
187.245

Writing units of the same order in the same column, as there are no thousandths in the minuend, we take of the 7 hundredths 1 hundredth, 10 thousandths; then, 5 thousandths from 10 thousandths leave 5 thousandths; 4 from (7—1, or) 6 leave 2; and so on, exactly as in Ex. 34, remembering also to place the decimal point directly under the points in the minuend and subtrahend.

49. Hence, to perform subtraction,

Rule.

1. Write the less number under the greater, units under units, tenths under tenths, etc., and draw a line beneath.

2. Beginning at the right hand, take each figure of the subtrahend from the figure above it, and place the remainder under the line, with the decimal point directly under the decimal points in the minuend and subtrahend.

3. If any figure in the subtrahend is greater than the figure above it, add ten to the upper figure and take the lower figure from the sum; write down the remainder and, considering the next figure in the minuend one less, proceed as before.
