• The term test will take place on Wednesday, February 25, 3:10-5pm in LM 159. It will cover sections 1-8 of the text   and  all the material of the lectures, tutorial and homework up to the end of this week. That includes: Induction, prime factorization,  modular arithmetic, Fermat's Theorem, Euler's theorem, Wilson's theorem, RSA encryption, Euclidean algorithm and its applications,  rational and irrational numbers. 
  
•  Here are four  practice tests for the term test. I will post solutions to them next week but please try to do all the problems by yourself before looking at the solutions. Also please note that some of the practice tests were for 50 minutes tests (while ours will be 1 hour 50 minutes) so they don't accurately represent the actual length of the term test.
  
• practice test 1
• practice test 2
• practice test 3
• practice test 4
  
•  There will be at least one homework problem on the test.
•  Rules for the test: No aids allowed. No calculators!
•  There will be no homework due the week of the term test. However, I recommend that you do the following problems  on recent material to help you prepare. You don't need to turn them in.
