I'm starting to learn CS all over again at the old age of 40, and had the pleasure to rediscover mathematics thanks to:
- Discrete Mathematics with Applications, by Susanna Epp, or
- Discrete Mathematics and Its Applications, by Kenneth Rosen (both have the same content, choose the style that you prefer), and
- Concrete Mathematics, by our lord and savior Donald Knuth.
I don't plan on reading TAOCP anymore as I would be dead by the time I finish reading everything else, but those introductory books are very good for beginners.
