Understanding Integers and Number Lines

This video tutorial explains how to add integers using a number line. It begins with a review of what integers are and how they are represented on a number line. The tutorial then demonstrates how to add positive integers by moving to the right and negative integers by moving to the left on the number line. Several examples are provided to illustrate the process, including adding positive, negative, and mixed integers. The video concludes with a brief mention of additional resources for further learning.
