Writing a Whole Number Using Digits

To convert a whole number from word form into digits, follow three steps. First, identify the words that name periods—such as "billion," "million," or "thousand"—keeping in mind that the ones period is never stated explicitly. Second, draw three blanks for each identified period and one set for the unnamed ones period, separating each group with commas. Third, write the digits corresponding to the value named for each period in the matching blanks, using leading zeros when a period's value does not fill all three places. This process reverses naming a number in words by using period keywords as clues to determine how many groups of digits are needed and where each value belongs.
