Adding Integers Using a Number Line

The video tutorial explains how to add integers using a number line. It begins with a simple example of adding 3 plus 3, demonstrating the process on a number line. The lesson then progresses to more complex examples, such as adding 4 and -7, and -1 and 5, illustrating each step on the number line. The tutorial emphasizes starting at zero and moving forward or backward based on the integers being added. By the end of the lesson, viewers will understand how to visually add integers using a number line.
