Pre-Algebra Lesson #2 How to Write a Number in Expanded Notation | Expanded Form of a Number

In this lesson, we will learn how to write a number in expanded notation, which is also known as expanded form. When we write a number in expanded notation, we are able to visually understand the value of each digit in a number. This maybe helpful to use when trying to learn concepts of addition and subtraction when regrouping is required.
