Understanding Expanded Form and Addition

The video tutorial teaches two-digit addition using expanded form. It begins with rewriting the equation, followed by writing each number in expanded form. The next step involves adding the expanded numbers and rewriting the equation to find the final answer. The tutorial emphasizes starting addition from the ones place.
