Adding and Subtracting on Number Line

The video tutorial teaches how to add negative numbers using a number line. It begins with an introduction to the concept and provides several examples and practice problems, such as adding -3 and 5, 4 and -5, 2 and -7, -6 and 4, -1 and 5, and -1 and -4. The tutorial emphasizes the direction of movement on the number line when adding positive and negative numbers.
