Project Euler is a fun way to motivate yourself to learn some algorithms, number theory, and a few other math topics, by solving programming puzzles: http://projecteuler.net/ http://projecteuler.net/ O'Reilly's Statistics in a Nutshell is a good stats textbook and reference, has some good exercises to be done in R (or S or Matlab), and is generally more programming-oriented than most statistics treatments. http://oreilly.com/catalog/9780596510497/ http://oreilly.com/catalog/9780596510497/ Two important classics are Knuth's The Art of Computer Programming (more algorithms/programming-focused; very steep learning curve) and Concrete Mathematics (with Ron Graham and Oren Patashnik; more math-focused; may be easier for self-study). Both have exercises you can work through, though many of the exercises are proofs (not easily translatable to programming).
