Rules of numbers Special Notes: 1. In American English, the order of large numbers is thousand, 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. 2. When saying large numbers, do not make thousand, million, billion, trillion, etc. plural. Not this: *twenty thousands dollars; *five millions people But this: twenty thousand dollars; five million people 3. In American English, use commas to separate thousands, millions, etc. Not this: *21.011 *31.256.721 *941.492.638.526 But this: 21,011 31,256,721 941,492,638,526 4. People often say a instead of one before hundred, thousand, etc. and they often add and before the last number: a hundred and twenty-one a thousand and eleven / etc.
