Writing a Whole Number in Words

To write a whole number in words, write the number in each period followed by
the name of the period. (The ones period is usually not written.) This same pro-
cedure can be used to read a whole number.

For example, we write 1,083,664,500 as

one billion,
Notice the commas
eighty-three million, after the name of each period.
six hundred sixty-four thousand,
five hundred

The name of the ones period is not used when reading and writing whole num-
bers. For example,
9,265
is read as

“nine thousand, two hundred sixty-five.”
