1. Read the number on the blackboard.

2. In 376, for what does the 6 stand? the 7? the 3? 3763 hundreds, 7 tens, 6 ones.

3. Read 3498. For what does each figure stand?

Each figure has a value that depends on its place in the number. The first place beginning at the right of a number is called ones' place; the second, tens' place; the third, hundreds' place; the fourth, thousands' place, etc.

4. Show that the left-hand 5 in the number 555 has a value, because of its place, that is 10 times the value of the middle 5, and 100 times the value of the right-hand 5.

A number containing more than four figures is often separated, for convenience in reading, into groups, or periods, of three figures each, beginning at the right. The name of the first period is units; of the second period, thousands; of the third period, millions.

The number on the blackboard above shows the arrangement of periods, and the three orders of figures in each. Beginning at the right, mark off into periods, and read:

Observe that zeros are enumerated but never read; that and is never read between integers; and that the first period is simply read but not named. Thus, 376 is read "three hundred seventy-six."

Write:

17. 10 thousand 4 hundred 6.

18. 150 thousand 5 hundred 25.

19. 5 million 825 thousand 5 hundred 4.

20. 5 million 25 thousand 3.
21. 2 million 22 thousand 60.
22. 6 million 27 thousand 9.
23. 5 million 5 thousand 5.
24. 8 million 8 thousand 85.
25. Ten thousand one hundred ten.
26. Five million two hundred fifty.
27. Six million six thousand six.

28. Sixty million one hundred fifteen thousand five.
29. Forty million four.

30. Ninety-nine million six hundred thousand nine. 31. Ninety-eight million one hundred fifty-four.

Read aloud. Then write the numbers from dictation: 32. There were 1,500,000 women in the United States engaged in war industries.

33. From 1907 to 1916 an average of 100,000,000 one-cent pieces was coined each year; in 1917 there were 213,500,000 cne-cent pieces coined; and in 1918 there were 445,228,201 pieces coined.

34. The boy scouts of America sold $17,000,000 worth of War Savings Stamps. They distributed 13,350,420 pledge cards averaging over $11 a card. They were awarded 2741 medals, 6679 bronze palms, and 8225 buttons.

35. Here are some of the requirements of an army of 5,000,000 men: 17,600,000 blankets, 7,978,000 overcoats, 33,000,000 pairs of shoes, 25,000,000 flannel shirts, 110,000,000 pairs of stockings, 7,000,000 campaign hats, 9,500,000 caps. 36. Write a problem containing numbers with nine figures

1. The dollar sign is $; it is placed before the number of dollars. The sign for cent or cents is ; it is placed after the number of cents.

When dollars and parts of a dollar are written as one number, a period, called a decimal point, separates the dollars from the cents. Cents are written in the first two places at the right of the decimal point. Thus, 7 dollars and 45 cents is written $7.45.

NOTE. Always read the word and between dollars and cents.

Parts of a dollar may be written in three ways. Thus, 18 cents may be written 184, $0.18, or $.18.

One tenth of a cent is called a mill. Mills are not coined; but they are used in many calculations. $.003 is read "3 mills," $.025 is read "2 cents 5 mills," $.184 is read "18 cents 4 mills."

2. Read in as many ways as you can:

3. Read; then write from dictation, using the dollar sign:

In business, the seller usually regards any part of a cent as an additional

cent.

Roman notation is used on many clock faces, as well as for chapter numbers in the Bible and other books, for inscriptions on monuments, etc.

1. Review the following Roman numbers:

On clock faces 4 is often written IIII.

The letter X stands for 10. Placing X before each of the Roman numbers in Ex. 1 makes the Roman numbers from eleven through nineteen. Thus, XI = 11, XIV = 14, XVI

16, XIX = 19.

2. Read: XII, XIII, XI, XV, XVI, XVII, XIX, XVIII. 3. Write all the Roman numbers from 11 through 19.

4. Copy and memorize the following numbers:

Placing each of the Roman numbers in Ex. 4 before the Roman numbers in Ex. 1 will make all the Roman numbers from twenty-one through ninety-nine. Thus, XXIV = 24, LVI = 56, XCIX

= 99.
