# In this Section:

In this section, we continue to learn about place value and our number system. We will learn how to write a number in expanded notation, also known as expanded form.
This method of writing a number emphasizes the place value of each and every digit of the number. This will help us to visually understand how each digit in a number gains its value. To write a
number in expanded notation, we form the sum of each digit multiplied by its corresponding place value (ones, tens, hundreds, thousands,…).
