Mastering Addition with Regrouping

The video tutorial explains how to add two numbers, 35 and 27, by breaking them into tens and ones. It demonstrates the process of adding the ones first, resulting in 12, and then carrying over 10 to the tens place. The tutorial further explains how to add the tens, resulting in a final sum of 62. The concept of carrying over, also known as regrouping, is highlighted as a key step in the addition process.
