The quiz on Friday 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 verbal and symbolic form. You may be asked to
produce examples or verify that something satisfies the requirements
of a definition. The definitions will be chosen from among:

*A*is a subset of*B*,*A*=*B**A*union*B*,*A*intersect*B*,*A*-*B*,*A*symmetric difference*B*,*C*_{X}(*A*)*P*(*A*)*A*x*B**P*<=>*Q*- Contrapositive, Converse, Inverse
- Negations of "and", "or", "for all", "there exists", "=>"
*x*is rational.- The sets
**N**,**Z**,**Q**,**R**,*c***N**,*c***Z**, Ø - Intervals (
*a*,*b*), [*a*,*b*], etc.
