How many are 63+ 79 +144 + 28? Ans. 314. 44. How many are 469874292748 +869 ? SUBTRACTION. 9. BY SUBTRACTION we take a less number from a greater number to find their difference. The greater number is called the MINUEND; the less number, the SUBTRAHEND; the difference, the REMAIN DER. 10. To subtract when no figure in the subtrahend is larger than the figure over it. Ex. 1. From 748 take 236. OPERATION. Minuend, 748 Subtrahend, 236 Taking 6 from 8 leaves 2, 3 from 4 leaves 1, and 2 from 7 leaves 5; therefore, the remainder is 512. Remainder, 512 2. WRITTEN ARITHMETIC. 12. A farmer bought a farm for $3625, and sold it for $4986; how much did he gain? Ans. $1361. 13. In 1860 the population of Maine was 628276, and that of New Hamsphire was 326072; how many more people were there in Maine than in New Hampshire? 11. To subtract when any figure in the subtrahend is greater than the figure over it. 14. From 982 take 137. OPERATION. Min. 982 Rem. 845 As we cannot take 7 units from 2 units, one of the tens is put with the two units, mak ing 12 units; and then 7 units from 12 units leave 5 units. Now as one of the 8 tens has been put with the 2 units, only 7 tens remain in the minuend, and 3 tens from 7 tens leave 4 tens; and, finally, 1 hundred from 9 hundreds leaves 8 hundreds; therefore, the entire remainder is 845. 12. In the same manner solve the following examples, taking each lower number from the one over it in each example; also subtract in the manner indicated by the signs. 15. { 6379 3245 8268 7614 5947 - 1072 8270 3948 2948 3749 3628 18. { 5402 4802 3712 824 59073764 4062 2983 7829 8037 784 4682 5643 8062 7864 5986 3784 2407 23.

A merchant sold goods for $3427, and thereby gained $1224; what did the goods cost him? 26.

How many years have passed since the discovery of America in 1492? MULTIPLICATION. 13. BY MULTIPLICATION we find how many units there are in any number of times a given number. The number to be repeated is called the MULTIPLICAND; the number which shows how many times the multiplicand is to be taken is called the MULTIPLIER; the result of the multiplication is called the PRODUCT. The Multiplicand and Multiplier are called FACTORS. 14. To multiply by a single figure. Ex. 1. In 1 bushel there are 32 quarts; how many quarts are there in 9 bushels ? OPERATION. Having set the factors as in the marMultiplicand, 32 gin, we say, 9 times 2 units are 18 units Multiplier, 9 1 ten and 8 units; write the 8 units Product, 288 in units' place, and then say, 9 times 3 tens are 27 tens, which, increased by the 1 ten previously obtained, make 28 tens = 2 hundreds and 8 tens, and these, written in the place of hundreds and tens respectively, give the true product, 288qt.

To perform Short Division. Ex. 1. How many weeks are there in 364 days? OPERATION. In dividing we first say, 7 in Divisor, 7)364 Dividend. 36, 5 times and 1 remainder; Quotient, 52 16.
