Adding a list of digits produces 'carries along the way. The distribution theory of carries involves the emerging theory of determinantal point processes (explanations provided). Thinking of carries as cocycles, the story extends to central extensions. There are also nice connections to Koszul algebras. This is joint work with Alexei Borodin and Jason Fulman.
