Understanding Subtraction with Number Line Models

The video tutorial explains how to use a number line model to solve subtraction problems. It introduces key terms such as 'menuend', 'scepter hand', and 'difference'. Two examples are provided: 8 - 5 = 3 and 17 - 6 = 11, demonstrating how to identify the menuend and scepter hand using arrows on a number line.
