Writing and saying large numbers in English.

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

Examples:

written

said

21,011

twenty-one thousand (and) eleven

1,256,721

one million two hundred (and) fifty-six
thousand seven hundred (and) twenty-one

(Note: The British use 'and' before tens and ones but the Americans usually leave the 'and' out.)

There are differences using large numbers in Europe and in America:

Europe America

1 000 000 million million

1 000 000 000 milliard billion

1 000 000 000 000 billion trillion
