Take the quiz on canvas about the Sage workshop (this helps me assess where the class is and also improve the worksheet for next time).
Read Chapter 5, from beginning to page 136 inclusive. Keep reading if you have time (if so, this will preview our next material).
Contemplate the question when can you solve a linear congruential equation (i.e. solve ax = b mod N)? Try to rephrase this problem into one just about integers.
Note, on the Resources page I now list tutors in MARC (and hours) where they know and are willing to teach number theory. Near the bottom.
IMPORTANT: Thursday’s office hours are 10:30-11:30 instead of 2-3 pm.
