The first number in the table is read: seven hundred forty-three trillion, nine hundred eighty-six billion, five hundred forty-three million, two hundred six thousand, seven hundred nineteen. Read the foregoing numbers, looking at the headings until you become familiar with the names of the periods. 23. When we read numbers, we begin at the right and separate the numbers into periods of three figures each. Then, beginning at the left, we read each period as if it stood alone, adding its name. Each period, except the highest or left-hand period, must contain three figures. 8. Erase the figure at the right hand of each number in 5, 6, and 7, arrange the remaining figures in periods anew, by placing commas where they belong, and then read the numbers. 9. Continue thus with the given numbers, erasing the figures one by one, pointing off into periods correctly, and reading the numbers. 10. Make the following numbers larger by one thousand.

Write the names of all the United States coins you have seen, and tell of what each is made. What paper money have you seen? In the currency of the United States, 10 mills make 1 cent. 100 cents make 1 dollar. 27. The Sign of Dollars is $. It is written before the number. Thus, $27 is read, twenty-seven dollars. 28. In writing cents and mills, a period called the Decimal Point is placed before the number of cents. 29. Cents occupy the first two places at the right of the decimal point, and mills the third place. Thus, $0.35 is read, thirty-five cents; $2.875 is read, two dollars eighty-seven cents five mills. Mills are not coined. In business five mills or more are called one cent, and less than five are disregarded. 30. If the number of cents is less than ten, a cipher must be written in the first place at the right of the decimal point. Thus, five cents is written $.05; three cents, 8.03; seven dollars two cents five mills is written $7.025. Write the following in columns, keeping decimal points in a vertical line: 1. Eighteen dollars twenty-four cents. 2. Twenty-six dollars thirty-six cents. 3. Fifty-one dollars five cents five mills. 4. Thirty-eight dollars sixteen cents three mills. 5.
