The video tutorial covers integer addition and subtraction, emphasizing changing subtraction to adding the opposite. It explains how to calculate the distance between numbers on a number line and introduces the concept of using absolute value for distance calculation. The tutorial also discusses vertical distance and change in elevation using a hiking example. Finally, it provides examples of using the distance formula and number line to find distances between numbers.
