Serge Lang Undergraduate Lecture: Adding numbers and shuffling cards

When numbers are added in the usual way, 'carries' appear along the way. It turns out that the carries form a Markov chain with an 'amazing' transition matrix. Strangely, this same matrix appears in the analysis of the usual way of shuffling cards (the seven shuffles theorem). I will explain all this 'in English'.
