Use Place Value to Name Whole Numbers<\/h2>\r\n

To write a number in words, write the number in each period followed by the name of the period without the \u2018s\u2019 at the end. Start with the digit at the left, which has the largest place value. The commas separate the periods, so wherever there is a comma in the number, write a comma between the words. The ones period, which has the smallest place value, is not named.<\/p>\r\n
