For Friday:

Proof for Feedback:

modular arithmetic (do this after tasks 1 & 2 below)

Tasks:

1. Watch my video about Modular Arithmetic (9:22).  It repeats some of what we did in class Wednesday, but repetition is a tried-and-true method of learning. 🙂
2. Do the associated practice-sheet (answer key at the back).
3. If time remains, watch the next follow-up video (17:26).  This covers why addition and multiplication are well-defined (in other words, why they “work” mod n).
4. Don’t forget that if you want to do a logic grade improvement, I’d like your study sheet by Friday.
