Finding Distance on a Number Line

The video tutorial explains how to find the distance between two points on a number line using absolute value. It begins with a problem statement and encourages viewers to solve it independently. The concept of absolute value is introduced as the positive distance from zero, emphasizing that distance is always positive. The tutorial then demonstrates how to calculate the distance between two points by counting units and using absolute value expressions. The solution is verified against given answer choices, and the correct expression is identified. The video concludes with a summary of the solution process.

What numerical expression represents the distance between -4 and 3?

Why is the expression '3 plus the absolute value of -4' equivalent to the distance found by counting?
