Directional decomposition is when we look at something and try to figure out which way it is pointing. We do this by breaking it down into smaller, simpler parts that we can understand. It's like taking apart a puzzle to see how it works.
Let's imagine we have a picture of a car driving down a road. We can break down the picture into different parts that help us understand where the car is going. For example, we can look at the wheels and see which way they are turning. We can look at the car's headlights and see where they are shining. We can even look at the road and see which way it's curving.
By looking at all these different parts, we can figure out which way the car is going. This is called directional decomposition, and it helps us understand things that might be complicated or hard to see at first glance.
