ABSTRACT
The material in this chapter is not the real stuff of discrete mathematics, but rather material you need to have under your belt to do discrete mathematics. Some of it, like this section, is probably review. Some, like Section 0.3 (Growth Rates and Order Notation) is probably quite new. Some, like Section 0.6 (The Language and Methods of Reasoning) probably contains material you have mostly seen, but organized differently and with advice that may be fresh. In any event, you can read this chapter first, or read it later piecemeal as needed.
