Fixed point combinator

A fixed point combinator is a special rule that is used in mathematical logic to solve complicated problems. It helps us break big problems into simpler parts that are easier to solve. It's like following a recipe to make a cake: if you try to mix everything together in one bowl, it won't turn out how you want it to. But if you break it down into steps, like adding the dry ingredients first, then the wet ingredients, then baking it in the oven, it will turn out just how you want it to! The fixed point combinator is a way of breaking down difficult problems so that you can make sense of them and figure out how to solve them.
