Understanding Absolute Value and Distance

The video tutorial explains how to find the distance between two numbers on a real number line. It begins by introducing the concept of distance and explores subtraction as a potential method. However, it highlights the issue of order affecting subtraction results. The tutorial then introduces absolute value as a solution, ensuring distance is always a positive number. Through examples, it demonstrates how to calculate distance using absolute value, regardless of the order of numbers. The video concludes with a practice problem for viewers to solve.
