Understanding Integers

This video tutorial introduces integers and explains how to compare and order them using a number line. The instructor uses a thermometer analogy to help students understand the concept of positive and negative numbers. The video covers how to determine which numbers are greater or smaller and how to use greater than or less than signs. It also demonstrates how to order integers from smallest to largest using a number line.
