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. 1. Multiply 421 by 3. EXPLANATION.–For convenience the Multiplicand 421 multiplier is written under the multipli cand. Beginning at the right hand each Multiplier 3 figure of the multiplicand is multiplied Product 1 263 by the multiplier. Thus 3 times 1 unit are 3 units. The 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. PROCESS. 1. How many are 8 times 196 ? EXPLANATION.For convenience the mul tiplier is written under the multiplicand. Be196 ginning at the right each figure of the multi8 plicand is multiplied by the multiplier. 1 5 6 8 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. 10. If a ship sails 368 miles in one week, how many miles will she sail in 7 weeks? 11. There are 5280 feet in a mile. How many feet are there in 9 miles ? 12.
