Exploring Positive and Negative Integers

The video tutorial covers adding positive and negative integers using number lines. It begins with an introduction to the lesson and explains key vocabulary terms such as value, integer, positive integer, negative integer, and number line. The tutorial demonstrates how to visualize integers on a number line and provides examples of adding both positive and mixed integers. A practice story problem is solved using a number line to illustrate the concept in a real-world context. The lesson concludes by emphasizing the usefulness of number lines in visualizing integer addition.
