Extension: This Puzzle came a little early, so
we will extend the due date untill Monday, Sept 25. Feel free to
resubmit if you jumped the gun with a poor answer.
Puzzle solutions are due by 9:00 AM on Monday of each week.
Puzzles are worth 5 points of extra credit each.
Answers must be accompanied by valid reasoning. Just like the tests, the answer alone isn't enough!
Each week, the first student to submit a correct answer will receive the stylish
152 T-shirt.
Previous winners get a "virtual t-shirt." No shirt, but a chance to win a prize with actual value at the end of the semester (often a book, or maybe software).
