The number to be taken or multiplied is called the Multiplicand. The number which shows how many times the multiplicand is taken is called the Multiplier. The result obtained by multiplying is called the Product. The Sign of Multiplication is an oblique cross: X. It is read times or multiplied by. 3 is written in units' place in the product. 3 times 2 tens are 6 tens. The 6 is written in tens' place in the product. 3 times 4 hundreds are 12 hundreds, which equal 1 thousand and 2 hundreds. The 1 thousand is written in thousands' place and the the 2 hundreds in hundreds' place in the product. Hence the product is 1263. PROCESS. 196 8 1568 EXPLANATION.-For convenience the mul tiplier is written under the multiplicand. Beginning at the right each figure of the multiplicand is multiplied by the multiplier. Thus, 8 times 6 units are 48 units. 48 units are equal to 4 tens and 8 units. The 8 is written in units' place in the product, and the 4 is reserved to add with the tens. 8 times 9 tens are 72 tens, plus the 4 tens reserved, are 76 tens. 76 tens are equal to 7 hundreds and 6 tens. The 6 is written in tens' place in the product, and the 7 is reserved to add with the hundreds. 8 times 1 hundred are 8 hundreds, plus 7 hundreds reserved, are 15 hundreds. 15 hundreds are equal to 1 thousand and 5 hundreds, which are written in hundreds' and thousands' places in the product. Hence the product is 1568. The accuracy of the work may be tested by reviewing it. 10. If a ship sails 368 miles in one week, how many miles will she sail in 7 weeks? 11.
