SIMPLE SUBTRACTION EACHETH to take a less number, called the subtra Then, from a greater of the same denomination, termed The minuend, and thereby to shew the difference. RULE. Put the less number under the greater, with units under units, tens under tens, &c. then begin at the right hand, and take the lower figure from that above it; but if it be greater than that above, take it from 10, and add the upper figure to the remainder, set down the result, and carry 1 to the next place; and so proceed. PROOF. Add the remainder to the less number, and the sum, if right, will be equal to the greater: Application. 1 Borrowed 10907. and paid 9091. how much remains ? answer 1811 2 A man was born in the year 1718, what is his age in the year 1810? answer 92 3 A boy who had one thousand nuts sold 286, gave away 60 and lost 437; how many had he left? answer 217 4 There were 4 bags, containing 1st. 34dols. 2d. 50dols. 3d. 100dols. 4th. 150dols. but one of them being lost, only 234 dols. remained; which bag was lost? answer 100d. bag. 5 Having a piece of ground 172 feet long, and rented to A at one end 57 feet, and to B 42 feet at the other end; how much was left between them? answer 73 feet.

SIMPLE MULTIPLICATION IS a concise way of adding numbers of the same name. The number arising from the operation is called the products Note. The multiplier and multiplicand are also calied factors, and the product is fometimes termined, fact, or rectan le. TABLE. 1 2 3 4 5 6 7 8 9 10 11 12 8|10|12|14|16| 18|20|22| 24 88 96 CASE CASE 1. When the multiplier does not exceed 12; RULE. Place the multiplier under the multiplicand; multiply the several figures successively from right to left, carry the tens, and set down the overplus as in addition. PROOF. Repeat the operation with the factors changed; Or, Multiply the double of one factor by half the other. When the multiplier is the exact product of two factors in the multiplication table; RULE. Multiply by one of said factors, and the product of that by the other; the last product will be that required. Note. When the multiplier exceeds 12, and is less than 20, multiply by the units figure, and add to the product of each figure that which is next on the right hand. EXAMPLES Make as many products as there are figures in the mul tiplier, omitting ciphers, and place the first figure of each product exactly under its multiplier; add the products to gether, and their sum will be the number sought. Note. If ciphers be in one or both factors at the right hand, annex them to the product. 1 Suppose 40 men were concerned in the payment of a debt, and each man paid 2564d. how much was the debt? answer 102560d. 2 How many square feet are in a floor 46 feet in length and 35 in breadth ? answer 1610 |
