At it its core, math is about numbers. Natural number arises from counting orders and naming convention for the uniqueness of a places in a sequence. In that sense, the physical world is a book written in natural numbers.
Using an analogy, the English alphabet has 26 letters, and with the alphabet infinite books can be written. We examine the books and find that each book consists at least one of the five vowels, and each word is less than 100 letters long, and so forth.
We are puzzled by how a random book can be that way. But need not be so, if we realize that the rule of writing a book is quite simple although the end product is somewhat complex. We start with a letter, then a word, and then a passage, a chapter and so on. Each step has some simple but irreducible rules. This process masks the simple relationship between a book and the alphabet, if we simple look at them without the steps in between.
