I understand how a number can function as code for a function or a machine, but how can a number be code for another number? You've said many times that all it takes for everything we see to exist are the natural numbers, addition and multiplication, but where/how do functions and machines enter in to the picture? It is clear to me how once we get to the objective existence of functions, we get the UDA, but I think I am missing some step. Is your point that with addition, multiplication, and an infinite number of successive symbols, any computable function can be constructed? Or do the relations imposed by addition and multiplication somehow create functions/machines?
