Understanding Expanded Form: A Guide to Writing Numbers in Their Component Parts

Expanded form is a way of writing a number in which it is expressed as the sum of its place values. For example, the number 456 can be written in expanded form as:

456 = 400 + 50 + 6

In this case, the number 456 is broken down into its hundreds (400), tens (50), and ones (6) components. This can be useful for understanding the individual parts that make up a larger number, and for performing arithmetic operations on those parts.
