Visualizing Integer Subtraction on a Number Line

This screencast explains integer subtraction using a number line. It covers two main cases: subtracting a larger number from a smaller one, which results in negative differences, and subtracting a smaller number from a larger one, resulting in positive differences. The video uses examples with both positive and negative numbers to illustrate these concepts. It concludes with encouragement to practice and revisit confusing parts.
