The quiz on Monday will consist of definitions, and will be brief. Your wording on a definition must be precise, and you will be required to give both a symbolic form and a verbal interpretation of the symbols. (Recall that an interpretation is a conceptual translation, not a symbolbysymbol transliteration.) You may be asked to produce examples or verify that something satisfies the requirements of a definition. The ideas you should know include:
A\subseteq B, A=B
A\cup B, A\cap B, AB
\P(A)
A\times B
P\iff Q
Contrapositive, Converse, Inverse
Negations of \vee, \wedge, \forall, \exists, \implies
x is rational
n\mathbin{}m
The sets {\bf N}, {\bf Z}, {\bf Q}, {\bf R}, \emptyset
