Subtracting Integers: The Number Line Visual that Helps it Make Sense

If you’ve ever struggled to explain subtracting integers on a number line, you aren't alone. In this video, I break down exactly why subtracting negative numbers like 4-(-6) can be so confusing and how a specific visual representation changed my entire perspective on the concept of "difference. Many textbooks and teachers explain this as a rigid procedure, but we’re going deep into the conceptual "why." By the end of this video, you’ll have a new mental model for subtraction that makes the math feel intuitive rather than forced—whether you're a student trying to pass a test or an educator looking for a better way to teach. What You’ll Learn: -How the number line can be looked at in different ways to show different relationships. -How to redefine "difference" to make 4-(-6) visually obvious. -A step-by-step walkthrough of 7 different number line manipulations. -How a growth mindset can help you master complex mathematical expressions.
