Submission Instructions

We invite readers to submit original problems appealing to students and teachers of advanced undergraduate mathematics. Problem proposals must be accompanied by solutions and any bibliographical information that will assist in their review. A problem submitted as a Quickie should have an unexpected, succinct solution. Submitted problems should not be under consideration for publication elsewhere. All contributions should be written in a style appropriate for publication in Mathematics Magazine.

We encourage electronic submissions of both problems and solutions as PDF files accompanied, when applicable, by TeX/LaTeX or other appropriate source files. Please use the appropriate form below to send us your Problem, Quickie or Solution.

**For proposal
submissions, click on "Mathematics Magazine Problem or Quickie
Proposal" below to access the submissions page. **

For **solution
submissions**, click on "Solution to Problem number x" that will
match the appropriate 4-digit problem number number.

Each problem featured in the Magazine is assigned a 4-digit number and the solutions are numbered according to the problem.

The statement of the problem as published has a typographic error. Point O₂ should be the circumcenter of triangle △ACE (not of triangle △ACD as published). We apologize for the mistake.
