Example of Expanded Form

Expanded form of whole numbers
In order to understand expanded form better, one needs to be good at place value.
Consider the number 543. Arrange the digits in a place value chart as shown below.
The value of 5 is 5 x 100 = 500
The value of 4 is 4 x 10 = 40
The value of 3 is 3 x 1 = 3
Therefore, the expanded form of the number 543 is 500 + 40 + 3.
Expanded form of decimal numbers
Consider the decimal 892.15. Arrange the digits in a place value chart as shown below.
From the chart above, we see that:
the value of 8 is 8 x 100 = 800
the value of 9 is 9 x 10 = 90
the value of 2 is 2 x 1 = 2
Therefore, the expanded form of the number 892.15 is 800 + 90 + 2 + 0.1 + 0.05.
