Understanding Addition Using a Number Line

The video tutorial explains how to perform addition using a number line. It begins with a basic example of adding 4 and 3, illustrating the concept of addends and the sum. The tutorial then provides two more examples: adding 9 and 7, and adding 12 and 19, each time demonstrating the process of moving along the number line to find the sum. The video emphasizes understanding the number line's structure, such as tick marks and labels, to accurately perform addition.
