Write whole numbers in expanded form

A whole number can be decomposed into the sum of the values represented by its digits in each place—for example, 52,406 = 50,000 + 2,000 + 400 + 6. This representation makes the base-ten structure and the role of zero as a placeholder explicit, supporting accurate comparison, computation, and later work with larger numbers; the scope is limited to whole numbers through 100,000, not decimal or more generalized expanded notation.

Detailed Explanation: Write whole numbers in expanded form

To write a whole number in expanded form, break it apart by place value. Write the value of each digit, then add the values together.

Example: Write $(63{,}042)$ in expanded form.

Identify the value of each digit:
- $6$ is in the ten-thousands place: $(60{,}000)$
- $3$ is in the thousands place: $(3{,}000)$
- $0$ is in the hundreds place: $0$
- $4$ is in the tens place: $(40)$
- $2$ is in the ones place: $2$
Add the place values:

63{,}042=60{,}000+3{,}000+0+40+2

Since adding $0$ does not change the number, the expanded form is usually written as:

\boxed{63{,}042=60{,}000+3{,}000+40+2}

The $0$ is a placeholder showing that there are no hundreds.
