Tree (set theory)

Tree is a way of organizing data. It's like a picture of all the things connected together. Every tree starts with a "root" at the top, which is the main point of the tree. Then the root has branches, which come out like the branches of a tree. Even further, the branches can have leaves, which are connected to the branches. Each leaf and branch has a connection or relationship with the root. For example, if the root is an animal, the branches might be its different parts (body, eyes, etc.), and the leaves could be the different types of animals (like cats and dogs). This type of organization makes it easy to find things and learn about different parts of the same thing.
