Writing and Saying Large Numbers

We don't normally write numbers with words, but it's possibleto do this--and of course this will show how we say the numbers.

In writing large numbers, American English uses a comma ( , )to separate thousands, millions, etc. American English also usesa hyphen ( - ) to separate "tens" words (twenty, fifty, etc.) and"ones" words (one, three, six, etc.)

1. In American English, the order of large numbers isthousand, million, billion, trillion, etc. (1,000; 1,000,000;1,000,000,000; 1,000,000,000,000; etc.)

In American English a thousand million is a billion,

but in British English, a thousand million is a milliard.

Special Notes:

2. When saying large numbers, do not make thousand,million, billion, trillion, etc. plural.Not this:*twenty thousands dollars; *five millions peopleBut this:twenty thousand dollars; five million people

3. In American English, use commas to separatethousands, millions, etc.Not this:*21.011*31.256.721*941.492.638.526But this:21,01131,256,721941,492,638,526

People often say "a" instead of "one" beforehundred, thousand, etc. and they often add"and" before the last number:a hundred and twenty-onea thousand and eleven / etc.

10 Rules for Writing Numbers and Numerals

1. Number versus numeral. First things first, what is the difference between a number and a numeral? A number is an abstract concept while a numeral is a symbol used to express that number. “Three,” “3″ and “III” are all symbols used to express the same number (or the concept of “threeness”). One could say that the difference between a number and its numerals is like the difference between a person and her name.

2. Spell small numbers out. The small numbers, such as whole numbers smaller than ten, should be spelled out. That’s one rule you can count on. If you don’t spell numbers out it will look like you’re sending an instant message, and you want to be more formal than that in your writing.

3. No other standard rule: Experts don’t always agree on other rules. Some experts say that any one-word number should be written out. Two-word numbers should be expressed in figures. That is, they say you should write outtwelve or twenty. But not 24.

4. Using the comma. In English, the comma is used as a thousands separator (and the period as a decimal separator), to make large numbers easier to read. So write the size of Alaska as 571,951 square miles instead of 571951 square miles. In Continental Europe the opposite is true, periods are used to separate large numbers and the comma is used for decimals. Finally, the International Systems of Units (SI) recommends that a space should be used to separate groups of three digits, and both the comma and the period should be used only to denote decimals, like $13 200,50 (the comma part is a mess… I know).

5. Don’t start a sentence with a numeral. Make it “Fourscore and seven years ago,” not “4 score and 7 years ago.” That means you might have to rewrite some sentences: “Fans bought 400,000 copies the first day” instead of “400,000 copies were sold the first day.”

5. Don’t start a sentence with a numeral. Make it “Fourscore and seven years ago,” not “4 score and 7 years ago.” That means you might have to rewrite some sentences: “Fans bought 400,000 copies the first day” instead of “400,000 copies were sold the first day.”

6. Centuries and decades should be spelled out. Use the  Eighties or nineteenth century.

7. Percentages and recipes. With everyday writing and recipes you can use digits, like “4% of the children” or “Add 2 cups of brown rice.” In formal writing, however, you should spell the percentage out like “12 percent of the players” (or “twelve percent of the players,” depending on your preference as explained in point three).

8. If the number is rounded or estimated, spell it out. Rounded numbers over a million are written as a numeral plus a word. Use “About 400 million people speak Spanish natively,” instead of “About 400,000,000 people speak Spanish natively.” If you’re using the exact number, you’d write it out, of course.

9. Two numbers next to each other. It can be confusing if you write “7 13-year-olds”, so write one of them as a numeral, like “seven 13-year-olds”. Pick the number that has the fewest letters.

10. Ordinal numbers and consistency. Don’t say “He was my 1st true love,” but rather “He was my first true love.” Be consistent within the same sentence. If my teacher has 23 beginning students, she also has 18 advanced students, not eighteen advanced students.
