Seattle Tour Math Opportunity ft. IMO Team Coach & CMU Prof. Po-Shen Loh


Memorial Weekend is just around the corner! While you celebrate the holiday and enjoy the long weekend, we’d also like to let you know about an exciting math opportunity happening this weekend!

If you’re interested in listening to a brilliant, eloquent, and enthusiastic math orator, come to the national tour of the one and only Po-Shen Loh, math professor at Carnegie Mellon University, long-time coach of the USA’s International Mathematics Olympiad team, founder of the educational program Expii and the contact tracing app NOVID. Prof. Loh is visiting the Seattle area over this weekend—registration and information can be found here (5/27 Bellevue 7PM, 5/30 Seattle 10AM, 5/30 Seattle 3PM). The last session might already be full; make sure to sign up quickly for the other two to secure a spot!

The 2021 HMMT/PUMaC TST has been concluded; solutions can be found here. If you did not take the TST and want to take a look at the problems, you can find the problems here.

2021-2022 Problem of the Month:


  • October's problem is written by Edward Yu. This particular problem is roughly early-AIME (American Invitational Math Exam) level and is a good example of fundamental geometry skills -- in particular, using similar triangles to compute areas. Take a look at the problem, does anything come to mind? If you want to read the problem in detail, you can find it here. Enjoy!

  • November's problem is written by Gene Yang. This problem is also roughly early-AIME (American Invitational Math Exam) level and is an excellent example of modular arithmetic. If you want to read the problem in detail, you can find it here. Enjoy!

  • December's problem is written by Alex Zhao. This problem is roughly mid-AIME (American Invitational Math Exam) level and is a good example of 3-D geometry in regular tetrahedra. Take a look at the problem; do any particular ideas come to mind? If you want to read the problem in detail, you can find it here. Enjoy!

  • January's problem is written by our student leader Michael Yang. This mighty geometry problem deals with a square inscribed in a quadrilateral; Michael provides a thorough and detailed analysis of the problem in the complex plane. The full solution can be found here. Enjoy!

  • February's problem is a geometry-flavored counting problem written by our awesome student leader Annabel Ge. The full solution can be found here. Enjoy!

  • March's problem is written by student leader Jason Cheng. It is a probability puzzle featuring a strangely weighted coin. The problem, with a full solution, can be found here. Enjoy!

  • April's problem, written by student leader Tristan Kay, is an intriguing probability dilemma involving an aimlessly wandering yak and a big bad wolf. This fun problem, with a full solution, can be found here.

  • May's problem, written by student leader Hongning Wang, is a very interesting algebra problem involving a magic number, and some connections to not-just-algebra. The problem and its full solution, can be found here.
