Notes on Writing Out Numbers:
1: It's correct to hyphenate all compound numbers from twenty-one (21) through ninety-nine (99). The hyphen is the minus sign, as in 'thirty-four' (34).
2: In American English, unlike British English, when writing out natural numbers of three or more digits, the word 'and' is not used after 'hundred' or 'thousand': so it is 'one thousand two hundred thirty-four' and not 'one thousand two hundred and thirty-four'.
3. Do not use commas when writing out in words numbers above 999: so it is 'one thousand two hundred thirty-four' and not 'one thousand, two hundred thirty-four'.
4. Use commas when writing in digits numbers above 999: 1,234; 43,290, etc.
