In a technical, legalistic sense, the semester started last week. But as far as I’m concerned, the semester doesn’t really begin until Problem of the Week returns!

Our theme for this semester: Clock Problems.

That’s not code for modular arithmetic or anything. I mean it literally. Every problem this term will feature clocks in some way. Some are fairly easy, some are a bit harder, though I wouldn’t say any of them are killer. Keep in mind that I deliberately keep the problems a little on the basic side, since I want students in the lower level math classes to be able to participate. So, nothing that requires anything more than algebra or geometry, and maybe some trigonometry.

You also do not need to worry that students will look on this blog and see the solutions put forward in the comments. Participation is entirely optional, and they are not receiving any sort of course credit for handing in a solution. The kind of student who enjoys participating in this is also the kind who will not be looking for a shortcut to the solution.

So feel free to have at it in the comments!
