119. Addition of denominate numbers is the operation of
finding a single number equivalent in value to two or more
given numbers. Such single number is called the sum.

How many pounds, shillings, and pence in 4 8s. 9c?.,
27 14s. lid., and 156 17s. lOd. ?

ANALYSIS. We write the units of the same OPERATION.

name in the same column. Add the column . s. d.

of pence ; then 30 pence are equal to 2 shil- 489

lings and 6 pence : writing down the 6, carrying 9 * -. - , ,

the two to the shillings. Find the sum of the JJ 1 J iL
shillings, which is 41 ; that is, 2 pounds and 1

shilling over. Write down 1*. ; then, carrying ^189 l s< g^
the 2 to the column of pounds, we find the
sum to be 189 Is. 6d.

NOTE. In simple numbers, the number of units of the scale,
at any place, is always 10. Hence, we carry 1 for every 10. In
denominate numbers, the scale varies. The number of units, in
passing from pence to shillings, is 12 ; hence, we carry one for
every 12. In passing from shillings to pounds, it is 20 ; hence, we
carry one for every 20. In passing from one denomination to
another, we carry 1 for so many units as are contained in the scale
at that place. Hence, for the addition of denominate numbers, we
have the following

RULE. I. Set down the numbers so that units of the
same name shall stand in the same column ;

II. Add as in simple numbers, and carry from one de-
nomination to another according to the scale.
PROOF. The same as in simple numbers.

124: SUBTRACTION OF

SUBTRACTION OF DENOMINATE NUMBERS.

120. The difference between two denominate numbers is
such a number as added to the less will give the greater.
SUBTRACTION is the operation of finding this difference.

I. What is the difference between 27 16s Sd and 19
17s. 9df.?

ANALYSIS. We cannot take 9rf. from Sd. ; OPERATION.
we therefore add to the upper number as many 20 12

units as are contained in the scale, and at the x** IDS. 8a.
same time add 1, mentally, to the next higher 19 17 9

denomination of the subtrahend. We then say, To rr~

9 from 20 leaves 11. Then, as we cannot sub-
tract 18 from 1C,' we add 20 and say, 18 from 36 leaves 18. Now,
as we have taken 1 pound=20 shillings, from the pounds, and
added it to the shillings, there are but 26 pounds left. We may
then say, 19 from 26 leaves 7, or 20 from 27 leaves 7. The lat-
ter is the easiest in practice.

The first step is called borrowing, the second, carrying : hence,

RULE. I. Set down the less number under the greater,
placing units of the same value in the same column.

II. Begin with the lowest denomination, and subtract as in
simple numbers, borrowing and carrying for each operation
according to the scale.

PROOF. The same as in simple numbers.

TIME BETWEEN DATES.
121. To find the time between any two dates.

1. What time elapsed between July 5th, 1848, and August
8th., 1850 ?

OPERATION.

1850 8 8
1848 7 5

NOTE. In the first date, the number of
the year is 1848 ; the number of the month
7, and the number of the day, 5. In the
second date, the number of the year is 1850,
the number of the month 8, and the number
of the day, 8.

Hence, to find the time between two dates :

Write the numbers of the earlier date under those of the
later, and subtract according to the preceding rule.

NOTE. 1. In finding the difference between dates, as in casting
interest, the month is regarded as the twelfth part of a year, and
as containing 30 days.

2. The civil day begins and ends at 12 o'clock at night.

2. What is the difference of time between March 2d,
1847, and July 4th, 1856?

3. What is the difference of time between April 28th, 1834,
and February 3d, 1856 ?

4. What time elapsed between November 29th, 1836, and
January 2d, 1854 ?

128 MULTIPLICATION OF

MULTIPLICATION OF DENOMINATE NUMBERS.

122. MULTIPLICATION of denominate numbers is the opera-
tion of multiplying a denominate number by an abstract number.

I. A tailor has 5 pieces of cloth each containing 6yd~
%qr. 3na. : how many yards are there in all ?

ANALYSIS. In all the pieces there are 5 OPERATION.
times as much as there is in 1 piece. If in yd. or. na.
1 piece each denomination be taken 5 times, it o 3
the result will be 5 times as great as the multi-
plicand. Taking each denomination 5 times,

we have 30#d. lO^r. 15?ia. 30 10 15"

But, instead of writing the separate products, 33 1 3
we begin with the lowest denomination and
say, 5 times 3na. are 15na. ; divide by 4, the units of the scale, write
down the remainder 3fta., and reserve the quotient Sgr. for the
next product. Then say, 5 times 2qr. are 10r., to which add the
%qr. making 13gr. Then divide by 4, write down the remainder
1, and reserve the quotient 3 for the next product. Then say, 5
times 6 are 30, and 3 to carry are 33 yards : hence,

RULE. I. Write down the denominate number and set
the multiplier under the lowest denomination.

II. Multiply as in simple numbers, and in passing from one
denomination to another, divide by the units of the scale, set
down the remainder and carry the quotient to the next product.

PROOF. The same as in simple numbers.

DIVISION OF DENOMINATE NUMBERS.

123. DIVISION of denominate numbers is the operation of
dividing a denominate number into as many equal parts as
there are units in the divisor.

1. Divide 25 15s. 4d. by 8.

ANALYSIS. We first say 8 into 25, 3 times OPERATION.

and 1 or 20s. over. Then, after adding the 8)d25 15s. la

15s. we say, 8 into 35, 4 times and 3s. over. ^ -j F~?

Then, reducing the 3*. to pence and adding in
the 4rf., we say, 8 into 40, 5 times.

123. What is division of denominate numbers? Give the rule for
division. How do you prove division ? How do you divide when the
divisor is a composite number ? What will be the unit of each quo-
tient figure ?

2. Divide 366tt. 3pfc. Iqt. by 7.

ANALYSIS. In this example we
find that 7 is contained in 36 bushels
5 times and 1 bushel over. Reducing
this to pecks, and adding 3 pecks,
gives 7 pecks, which contains 7, 1
time and no remainder. Multiplying
by 8 quarts and adding, gives 7
quarts to be divided by 7.

Hence, for the division of denominate numbers we have the
following

RULE. I. Begin with the highest, denomination and
divide as in simple numbers :

II. Reduce the remainder, if any, to the next lower de-
nomination, and add in the units of that denomination for
a new dividend.

III. Proceed in the same manner through all the denomi-
nations.

PROOF. By multiplication, as in simple numbers.

NOTES. 1. If the divisor is a composite number, we may divide
by the factors in succession, as in simple numbers.

2. Each quotient figure has the same unit as the dividend from
which it was derived.

3. If the divisor is greater than 12 and not a composite number,
the operation is the same as long division.
