The decimal number system is a base 10 system, so the digits of each place can be any number from 0 to 9. Each place value has a name.

For large numbers, digits are separated by commas or spaces into groups of three, called periods. For example,

\[12,340,982\qquad 320\,432\,196\]

`Example 1`

Name the following number: \(384,341\)

`Solution`

Three hundred eighty-four thousand, three hundred forty-one.

`Example 2`

Write out the following number: Twelve million, thirty-eight thousand, two

`Solution`

\(12,038,002\)

Note there is no **and **separating periods. The word **and** is reserved for decimal place values after the ones column.

`Example 3`

What place value is underlined for the following numbers:

a. \(820,3\underline{3}0,020\) - *ten thousands*

b. \(\underline{4}032\) - *thousands*

c. \(1,402,\underline{4}97\) - *hundreds*
