none (test on Relations wednesday)


  • You have a test on Relations Wednesday.  There are practice problems on the Materials Archive tab.  You can also re-read Hammack, Chapter 11 and do exercises there.
  • Late addition/notice/clarification:  I will also test modular arithmetic (I forgot to include some practice problems in the practice problems sheet, but see Hammack, 11.5 and its exercises.  Know how to do modular arithmetic.
