It is a math heavy set, but as you go further on, there is more programming - but still nothing like the programming that you and I would do. He's focused on hyper-optimizing sorting routines, random number generators, hashmaps, and high-precision arithmetic. It's actually really fascinating stuff, and the sort of thing you just don't really see anywhere else (for example, did you know you can actually test the randomness of a random number generator?) But yes, he's more focused on the math behind computer science than the programming itself; besides his elevator simulator, I think the longest program in the entire first three volumes was his AVL tree implementation, which is still something that most of us encounter in data structures 101 nowadays.
