Hi everyone!

An email was sent to the administrators on the mailing list with PDFs of the first round. The email included instructions for proctoring the exam, the 10-quesiton exam and the answer sheet.  Print and make copies as appropriate for the students taking the exam.  All answers are submitted through an online form (click on “answer form” and then click the link.  Alternatively, the instructions page has a hyperlink).  If you didn’t receive the email sent this morning (Oct. 26th), please send me an email at so I can send you the information.

And with that, I bid a farewell

Hi All,

Well, we did it! We successfully had a fun contest, with 165 participating in the final round. Lunch, prizes and t-shirts were given, and it was a grand old time. I thank everyone who helped and participated in this wonderful endeavor. It was an absolute dream being in charge of such an adventure in educational organization.

This will be my only year of supervising the Math Contest for UNC. I have accepted a faculty position in Pennsylvania starting Fall 2022. The highly esteemed mathematics professors that wrote the exam questions will still be at UNC, but somebody else will be director of the contest itself. I will be available to serve as a legacy consultant from afar, to help whoever takes over the contest.

I have written a manual on how to organize a math contest, specifically the UNC Mathematics Contest. It is my goal that the next director will continue in the vision I had for the contest.

Please let me know if you have any questions.

Preliminary Results

Hi All,

Thank you for taking part in the UNC Math Contest!  I now have the first round of results.  I’m going to write up complete results and solutions documents, but that will take a while.  I went through the exams and did the results on the first 10 questions, separating by score and grade. 

But first, a correction to the solutions from the previous email.  A second solution was found to the second problem, so I included answers to questions 1-10 below.

Question 1 – 6
Question 2 – 11 or 14
Question 3 – 29 inches
Question 4 – 9271 (fraction was 1023/8248)
Question 5 – 5825
Question 6 – 84
Question 7 – 300
Question 8 – 42  (9 + 10 + 11 + 12)
Question 9 – 149
Question 10 – 10369

On to the results!

A total of 164 students participated in the exam.  There were 3 perfect scores of 10/10.  Below is the distribution of scores.  I will have each score separated by grade in the final results document.

10/10 – 3
9/10 – 12
8/10 – 5
7/10 – 6
6/10 – 8
5/10 – 17
4/10 – 30
3/10 – 29
2/10 – 31
1/10 – 8
0/10 – 5

We had students from 4th grade to 12th grade participate.  Below is a distribution of grades.

12th grade – 15
11th grade – 25
10th grade – 23
9th grade – 26
8th grade – 35
7th grade – 19
6th grade – 9
5th grade – 0
4th grade – 1

Okay, that’s all for now.  Expect an email relatively soon with the solutions and a more detailed report on the results.

Bye for now,

The Contest is OVER!

And what a show it was!

Hi Everybody!

This is Dean Zeller, Director of the UNC Math Contest. As you may know, our contest was Saturday, February 26th. Over 150 middle- and high-school students from around Colorado and Wyoming drove to UNC campus to celebrate the event.

The final count was 158, with 230 people total joining us for lunch. It kept me in nerves, but came together well at the end. The crowd appreciated the results, and the students were happy with their chosen prizes.

This week, I will put together a final outline of results, answers, proofs, and other clean-up affairs necessary for the contest. Please be patient, as I have four college-level classes that need my attention.

The most common question among my emails so far is: What are the answers? Now that the contest is over and prizes have been awarded, here are the answers to to the first 10 questions. I will see if I can get formal proof answers for questions 11-13.

So, with that, expect a few more postings and emails over the next week. If you have any requests for something to include in the post, I’ll do my best.



Answers to the Math Contest (#1-10)

  1. 6
  2. 11 or 14 were both accepted as correct answers
  3. 29 inches
  4. 9271  (1023/8248 is the fractional form))
  5. 5825
  6. 84

The Countdown Begins…

Hello All,

Okay, the time has come!  The Mathematics Contest for UNC is less than a month away.  The final round will happen on campus in McKee Hall 150 on Saturday, February 26th.  Here is hoping the weather is agreeable for those that have to drive.

This posting went out to everyone on the mailing list, those that made the cutoff, and the wildcards.  If you think someone didn’t see this posting that should have, feel free to forward.

The tentative testing schedule is as follows:

  • 8:00-9:00 Meet in McKee 150, 151, and 152
  • 9:00-12:00 Exam time
  • 12:00-1:00 Lunch provided at cafeteria
  • 1:00-2:00 Guest speakers
  • 2:00-3:30 Awards ceremony

While the contest is a month away, it will go fast.  Feb 26th will be on us before we know it.

Please let me know if you have any questions.  I will likely send out another reminder in a week or two, just in case arrangements have changed.
