The list of winners of the 25th Annual UNC State Math Contest is below. Congratulations to the top scorers!
Dr. Ming Song has kindly prepared a beautiful set of solutions. Rocke Verser has also generously prepared comments on several of the problems.
Four students successfully counted the number of triangles formed by chords in a circle, Problem 9. Nine students correctly answered the question about the Fibonacci polynomials, Problem 8. There were several very good ways to do that problem. Twelve students named powerless arithmetic sequences, Problem 10. Thirteen students correctly counted the number of factorizations of 4096 into squares and cubes, Problem 11a. One student almost perfectly counted the factorizations of 46,656 into squares and cubes and several more showed reasonable plans for the count.
As always, we have enjoyed looking at the papers. These students do excellent work. We are astonished at what they can accomplish in three hours. We look forward to next year.
Solutions coming soon. When the papers are graded we will post the results here and email registered participants.
The 2017 Final Round will be one hour later than it has been in previous years. This year the contest is 1:45-5pm. This is to avoid conflict with the SAT in the morning.
The Final Round is in Greeley this coming Saturday, January 21, 2017 in McKee Lecture Hall, L150-L152. Directions are here. If you plan to come, please register on the registration tab. It is not too late to petition to come.
As usual, there will be a solutions seminar for families and teachers during the contest. We will discuss the problems. Check here for directions to the seminar.
The contest is pencil and paper only. Do not plan to use a calculator or phone during the contest. There will be clocks visible in the contest room. You may bring snacks, but please do not share with other participants during the contest. Pencils and blank paper will be provided. All you need to bring is your brain. You may leave the contest room when you finish working, but please make your post-contest arrangements with other participants before work begins. After work begins, there should be no more communication between participants inside the contest room.
Writing these contests is a way for us to share with you some of the beauty in mathematics. We hope you enjoy them in this spirit.
We look forward to seeing you in Greeley on Saturday.

A good time was had by all. Nice seminar. Nice work. Contest results will be out soon. We are working on them. Here are the contest questions, the solutions written by the question writers, and solutions written by math coach Ming Song:
