BIG NUMBERS

English people don't normally write numbers with words, but it's possible to 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 uses a hyphen ( - ) to separate "tens" words (twenty, fifty, etc.) and "ones" words (one, three, six, etc.) Examples: Group 1 written said 1,011 one thousand eleven 21,011 twenty-one thousand eleven 721,011 seven hundred AND twenty-one thousand eleven Group 2 written said 1,256,721 one million two hundred AND fifty-six thousand seven hundred AND twenty-one 31,256,721 thirty-one million two hundred AND  fifty-six thousand seven hundred AND twenty-one 631,256,721 six hundred AND thirty-one million two hundred AND fifty-six thousand seven hundred AND twenty-one Group 3 written said 1,492,638,526 one billion four hundred AND ninety-two million six hundred AND  thirty-eight thousand five hundred AND twenty-six
