Adding and Subtracting Integers Challenge

This video tutorial covers lesson three on adding and subtracting positive and negative numbers. It combines lessons one and two, focusing on the rules for adding and subtracting integers, such as 'same signs add and keep' and 'different signs subtract.' The tutorial also explains the concept of difference without using absolute values and discusses changes on a number line, emphasizing the importance of direction and starting point. The video includes examples and encourages students to practice problems and engage with interactive questions.
