Smith DIVISION OF SIMPLE NUMBERS. $39. Having two unequal numbers, we may subtract the lesser from the greater. If the remainder be greater than the least number, that number may be subtracted from it, and these subtractions may be continued till the remainder becomes the least. For example, take the numbers 12 12 and 4. Having taken 4 from 4 12, the remainder is 8: which, be 8 lst remain. ing greater than 4, 4 can be again 4 subtracted. The second remain 4 2d remain. der is 4; and from this, 4 can be 4 again subtracted, and the third remainder is 0. Now the number 0 3d remain. 4 has been taken three times from 12. The number 12, therefore, contains 4 three times, er. $ 40. Take the numbers 27 and 27 8. In this example, 8 is taken 3 8 times from 27, and there is a re 19 1st remain. mainder of 3. 8 By continued subtraction we 11 2d remain. can always find how many times 8 one number is contained in another, and also, what is left when it 3 3d remain. is not contained an exact number of times. We can arrive at the same result by a shorter method, called Division. § 41. DIVISION explains the manner of finding how many times a less number is contained in a great It is a short method of subtraction. The number expressing how many times the di. vidend contains the divisor, is called the quotient. The number which is left, when the dividend does not contain the divisor an exact number of times, is called the remainder. § 42. There are three signs used to denote division. They are the following: 18-4 expresses that 18 is to be divided by 4. y expresses that 18 is to be divided by 4. 4)18 expresses that 18 is to be divided by 4. When the last sign is used, a curved line is also drawn on the right of the dividend to separate it from the quotient, which is generally set down on the right. Let the following table be committed to memory. It is read 2 in 2, 1 time; 2 in 4, 2 times, &c.

Divide 86 by 2. Place the divisor on the left of the divilend, draw a curved line 2) 86 between them, and a straight line 43 quotient. under the dividend. Now, there are 8 tens and 6 units to be divided by 2. We say, 2 in 8, 4 times, which being 4 tens we write the 4 under the tens. We then say, 2 in 6, 3 times, which are 3 units, and must be written under the 6. The quotient therefore, is 4 tens and 3 units, or 43. 2. Divide 729 by 3. 3) 729 tens and 9 units, all to be divided by 3. Now, Set 243 we say 3 in 7,2 times and 1 over. down the 2, which is hundreds, under the 7. But there is 1 hundred or 10 tens not yet divided. We put the 10 tens with the 2 tens, making 12 tens, and then say, 3 in 12, 4 times, and write the 4 in the quotient, in the tens place; then say 3 in 9, 3 times. The quotient therefore is 243. 3. Divide 729 by 9. In this example we say 9 in 7 we cannot, but 9 in 72, 8 times, which are 8 tens: then 81 9 in 9, 1 time. "The quotient is therefore 81. 9) 729 |
