Expanded form

Expanded form is a way of writing a number as the sum of its individual digits multiplied by their place value.

For example, let's take the number 345.

In expanded form, it can be written as:
300 + 40 + 5

Similarly, the number 2,567 can be written in expanded form as:
2000 + 500 + 60 + 7

Expanded form is helpful in understanding the value of each digit within a number and can be used to perform addition or subtraction of multi-digit numbers.
