In this video, we break down the concept of percentage change into clear, easy steps using everyday examples. We start by understanding what change means in a quantity—whether it's an increase or a decrease—and how to measure that shift. Then we quickly recall the idea of percentage as a way to express parts of a whole out of 100. With that foundation, we dive into the formula to calculate percentage change using the difference between the final and original values. To bring it all together, we walk through a practical example—calculating the percentage discount on a sale item—so you can see exactly how the math works in real life.
