OPERATION.

15 Product.

From the first of these examples we see, that the product
of 4 multiplied by 3, is 12, the number which arises from
taking 4, 3 times ; and that the product of 5 by 3 is equal to
15, the number which arises from taking 5, three times :
hence,

MULTIPLICATION is the operation of taking one number as
many times as there are units in another.

The number to be taken is called the multiplicand.

The number denoting how many times the multiplicand is
taken, is called the multiplier.

The result of the operation is called the product.

The multiplicand and multiplier are called factors, or pro-
ducers of the product.

46. We also see, from the above examples, that 4 taken
3 times, gives the same result as is obtained by adding three
4's together ; and that 5 taken 3 times gives the same result
as is obtained by adding three 5's together : hence,

45. What is Multiplication ? What is the number called which is to
be taken? What does the multiplier denote? What is the result
called ? What are the multiplier and multiplicand called ?

46. What is 4 multiplied by 3 equal to ? What is 5 multiplied by 3
equal to ? How then may multiplication be di -lined ?

SIMPLE NUMBERS. 45

MULTIPLICATION is a short method of addition.

47. The sign x, placed between two numbers, denotes
that they are to be multiplied together. It is called the sign
of multiplication. Also, ( 4 -f 3 ) x 5, denotes that the sum of 4
and 3 is to be multiplied by 5.

9x8= 72.
Ix2x 3= 6.
Ix4x 5= 20.
2x6x 5= 60.

4x3x11= how many ?

5 x 2 x 9 = how many ?

6 x 2 x 5 = how many ?

7 x 8 = how many ?
1 x 6 x 9 = how many ?

7 x 1 x 12= how many ?
9 x 1 x 9= how many ?

11 x 1 x 7 = how many ?

12 x 1 x 5= how many ?

NOTE. There are three parts in every operation of multiplica-
tion. First, the multiplicand: second, the multiplier: and third,
the product.

48. The product of two factors is the same, whichever be
taken for the multiplier. / (

For, let it be required to multiply 5 by 3.

OPERATION.

ANALYSIS. Place as many 1's in a ,5
horizontal row as there are units in the ,

multiplicand, and make as many rows as Mill!

there are units in the multiplier : the \ |

product is equal to the number of 1's in o -j 1

one row taken as many times as there are ( 1 11 1 1

rows : that is, to x 3=15. JT

But if we consider the number of 1 s in a vertical row to be
the multiplicand, and the number of vertical rows the multiplier,
the product will be equal to the number of 1's in a vertical row
taken as many times as there are vertical rows ; that is, 3 x 5=15 :
and, as the same may be shown for any two numbers,

The product of two factors is the same whichever factor
is used as the multiplier.

47. What is the sign of multiplication ?

NOTE. How many parts are there in any operation of multiplica-
tion ? What are they ?

48. What is the product of 3 by 4 ? Of 4 by 3 ? Is the product
altered by changing the order of the factors ?

4:6 MULTIPLICATION.

EXAMPLES.

3x7 = 7x3 = 21: also, 6x3 = 3x6=18.

9 x 5=5 x 9=45 : also, 8 x 6=6 x 8 = 48.

and, 8x7 = 7x8=56: also, 5x7 = 7x5 = 35.

ANALYSIS. It is required to take 230 4 OPERATION.
times. If the entire number is taken 4 times, 236
each order of units must be taken 4 times : 4.
hence, the product must contain 24 units, 12 -
tens, and 8 hundreds ; therefore, the product 24 units.
is 944. 12 tens.

It is seen, from the preceding analysis. 8 _ hundreds.
that, 944" Product.

1. If units be multiplied by units, the unit of the product
will be 1.

2. If tens be multiplied by units, the unit of the product
unit be 1 ten.

3. If hundreds be multiplied by units, the unit of the
product will be 1 hundred ; and so on :

And since the product of the factors is the same whichever
is taken for the multiplier (Art. 48), it follows that,

4. If units of the first order be multiplied by units of a
higher order, the units of the product will be the mme as
that of the higher order. /

The operation in the last example may be performed ia
another way, thus :

ANALYSIS. Say 4 times 6 are 24 : set down the OPERATION.
4, and then say, 4 times 3 are 12, and 2 to carry 236

are 14 ; set down the 4, and then say, 4 times 2 are 4

8, and 1 to carry are 9. Set down the 9, and the
product is 944 as before.

The method of carrying is the same as in addition.

50. Spelling, IP multiplication, is naming the two factors
which produce the product, as well as the words which in-
dicate the operation ; whilst the reading consists in naming
only the word which expresses the final result.

ANALYSIS. In multiplying 8325 by 6, we say, OPERATION.
6 times 5 are 30 ; then, 6 times 2 are 12 and 3 to 8325

carry are 15 ; 6 times 3 are 18 and 1 to carry are 6

19 ; C times 8 are 48 and 1 to carry are 49.

This is the spelling. The reading consists in pronouncing
only each final word which denotes the result of an operation
thus : thirty, fifteen, nineteen, forty-nine.

With a little practice, the pupils will perform the operations
mentally, and read with great facility, either separately or in
concert in classes.

48 MULTIPLICATION.

ANALYSIS. The multiplicand is to be taken 603 R90 1
times. Taking it 3 times we obtain 24612.

When we come to take it 6 hundreds times, the _ 5__

lowest order of units will be hundreds: hence, 4, 24612

the first figure of the product, must be written in 10091
the third place.

4947012

NOTE. The product obtained by multiplying by a single figure
of the multiplier, is called a partial product. In the above ex-
ample there are two partial products, 24612 and 49224. The
sum of the partial products is equal to the result or product sought :
hence, the following

RULE I. Write the multiplier under the 'multiplicand,
placing units of the same order in the same column.

II. Beginning ivith the units' figure, multiply the entire
multiplicand by each figure of the multiplier, observing to
write the first figure of each partial product directly under
its multiplier. ,

III. Add the partial products and their sum will be
the product sought.

PROOF.

52. Write the multiplicand in the place of the multiplier
and find the product as before. If the two products are the
same, the work is supposed to be right.

NOTE. This proof depends on the principle that the product of
two numbers is the same whichever is taken for the multiplicand
(Art. 48) ; and also on the fact, that the same error would not be
likely to occur in both operations.

CONTRACTIONS IN MULTIPLICATION.

finding the product when the multiplier is a composite num-
ber.

50 MULTIPLICATION.

CASE I.

Of Components or Factors.

54. A composite number is one that may be produced by
the multiplication of two or more numbers, which are called
components or factors.

Thus, 2 x 3=6. Hence, 6 is the composite number, and 2
and 3 are its components or factors.

The number, 16=8x2: here 16 is a composite number,
and 8 and 2 are the factors. But since 4 x4=16, we may
also regard 4 and 4 as factors of 16.

Again, 16=8x2, and 8 = 4x9 = 2x2x2: hence,
16=2x2x2x2: therefore, 16 has also four equal factors.

1. What are the factors of 8 ? of 9 ? of 10 ? of 12? of 14?
of 18 ? of 24 ?

2. What are the factors of 20 ? of 21 ? of 22 ? of 26 ; of
25? of 30?

3. What are the factors of 36 ? of 42 ? of 44 ? of 49 ? of
56? of 64? of 72?

4. Let it be required to multiply 8 by the composite num-
ber 6, of which the factors are 2 and 3.

(11111111) 48

If we write 6 horizontal lines with 8 units in each, it is
evident that the product of 8 x 6=48 will express the num-
ber of units in all the lines.

Let us first connect the lines in sets of two each, as at the
right ; the number of units in each set will then be expressed
by 8 x 2=16. But there are 3 sets ; hence, the number of
units in all the sets is 16 x 3 = 48.

54. What is a composite number ? Is 6 a composite number ? What
are its components or factors ? What are the factors of the composite
number 16 ? What are the factors of the composite number 12 ? How
do you multiply when the multiplier is a composite number?

SIMPLE NUMBERS 51

Again, if we divide the lines into sets of 3 each, as at the
left, the' number of units in each set will be equal to
8x's=24, and since there are two sets, the whole number
of units will be expressed by24x2=48.

Since the product of either two of the three factors 8, 3 and
2, win be the same whichever be taken for the multiplier
(48), and since the same principle will apply to that product
and the other factor, as well as to any additional factor, if
introduced, it follows that,

The product of any number of factors will be the same
in whatever order they are multiplied : hence, the following

RULE. I. Separate the composite number into its factors.

II. Multiply the multiplicand and the partial products
by the factors, in succession, and the last product mill be the
entire product sought.

EXAMPLES.

1. Multiply 327 by 12.

The factors of 12 are 2 and 6 ; they are also 3 and 4 ; or
fhey are 3, 2 and 2.

For, 2x6 = 12, 3x4 = 12, and 3x2x2 = 12.

2. Multiply 5709 by 48.

3. Multiply 342516 by 56.

4. Multiply 209402 by 72.

5. Multiply 937387 by 54.

6. Multiply 91738 by 81.

7. Multiply 3842 by 144.

CASE II.

55. When the multiplier is 1, with any number of ci-
phers annexed, as 10, 100, 1000, &c.

Placing a cipher on the right of a number, is called an-
nexing it. Annexing one cipher increases the unit of each
place ten times : that is, it changes units into tens, tens into
hundreds, hundreds into thousands, &c. ; and therefore in-
creases the number ten times.

Thus, the number 5 is increased ten times by annexing one
cipher, which makes it 50. The annexing of two ciphers

55. If yon place one cipher on the right of a number, what effect has
it on its value ? If you place two, what effect has it ? If you place
three ? How much will each increase it ? How do you multiply by
10, 100, 1000, &c ?

52 MULTIPLICATION.

increases a number one hundred times ; the annexing of three
ciphers, a thousand times, &c. : hence the following

RULE. Annex to the multiplicand as many ciphers as
there are in the multiplier, and the number so formed will
be the required product.

EXAMPLES.

1. Multiply 254 by 10.

2. Multiply 648 by 100.

3. Multiply 7987 by 1000.

4. Multiply 9840 by 10000.

5. Multiply 3750 by 100.

6. Multiply 6704 by 10000.

7. Multiply 2141 by 100.

8. Multiply 872 by 100000.

CASE III.

56. When there are ciphers on the right hand of one or
both of the factors.

In this case each number may be regarded as a composite
number, of which the significant figures are one factor, and
1, with the requisite number of ciphers annexed, the other.

1. Let it be required to multiply 3200 by 800-

OPERATION.

3200=32 x 100 ; and 800=8 x 100 ;
Then, 3200 x 800 = 32 x 100 x 8 x 100
= 32x8x100x100
= 2560000.

Hence, we have the following

RULE. Omit the ciphers and multiply the significant
figures : then place as many ciphers at the right hand of
the product as there are in both factors.

APPLICATIONS IN MULTIPLICATION.

57. The analysis of a practical question, in Multiplication,
requires that the multiplier be an abstract number ; and then
the unit of the product will be the same as the unit of the
multiplicand.

Thus, what will 5 yards of cloth cost at 7 dollars a yard ?

ANALYSIS. Five yards of cloth will cost 5 times as much as
1 yard. Since 1 yard of cloth costs 7 dollars, 5 yards will cost
5 times 7 dollars, which are 35 dollars.

The cost of any number of things is equal to the price
of a single thing multiplied by the number.

But we have seen that the product of two numbers will be
the same, (that is, will contain the same number of units)
whichever be taken for the multiplicand (Art. 48). Hence,
in practice, we may multiply the two factors together, taking
either for the multiplier, and than assign the proper unit to
the product, We generally take the least number for the
multiplier.
