Category theory

Category theory is a way of analyzing math problems by breaking them down into simpler parts. Instead of seeing math as just numbers or equations, it is seen as collections of objects and relationships between them. To explain this to a 5-year-old, you could say that category theory is like a map. The map has different shapes (like squares, circles, and triangles) that represent different objects in the math problem, and it also has lines connecting them, which represent the relationships between the different objects. By looking at the pattern of objects and relationships and understanding how they connect to each other, math problems can be solved more quickly and easily.
