Absolute Difference and Integer Addition

The video tutorial continues the topic of integers, focusing on adding them. It begins with a recap of the previous video and introduces two methods for adding integers: using a number line and a preferred method involving absolute differences. The number line method is demonstrated with small numbers, while the preferred method is suitable for both small and large numbers. The video concludes with a preview of the next topic, which will cover subtracting integers.
