Past Assignments
24 August
Tuesday's online office hours 10-12 are at: https://meet.google.com/ywx-xbsw-pkr
27 August
Read: chapter 1.

Practice: Hand in at the beginning of class your answers to problems 1-5 at the end of chapter 1. Each of these problems asks you to come up with 5 examples; to make the homework shorter, for each problem just come up with 2 examples for each of the 5 problems (so 10 cases total). Handwritten is acceptable (for many of our later homeworks there are special symbols or tables and it is too much work to try to type them). Try problem 6 if you like, as extra-credit.

3 September
Practice: Complete problems 3, 4, and 6 at the end of chapter 2.

I've been asked about how to do this. For each problem (that, is for 5 and then for 6) make one translation key, showing what each atomic sentence letter means in English. Each atomic sentence in your key should correspond to an atomic sentence in English. So, look through the problems we are skipping in 5 (a-j), identify all the atomic sentences, write them down, and tell me which letter corresponds to each sentence. Your key will look like:
KEY
LOGIC ...... ENGLISH
P: Josie is a cat.
Q: Josie is a mammal.
R: Josie is a fish
...
Then, after having done that, and using your key, translate all those sentences. Do the same again for 6.) Not need to write the English sentences out, but be sure to properly label which subquestion you are answering each time. E.g., 6a, 6b, 6c, etc. So the answer to 5d using our key above would have been:
5.d. (¬ P → ¬ Q)
