Readers are invited to send their solutions to any of the problems published in Crux Mathematicorum. We also welcome your problem proposals and articles, as well as comments and suggestions. For the problems in Skoliad we are looking especially for solutions from pre-university students.

On any correspondence, please give your name, school or other affiliation (if applicable), city, province or state, and country. Pre-university students should also include their grade in school. Please address your correspondence to the appropriate editor, as listed below.

Correspondence may be sent by email or regular mail (but not by FAX). Material sent by regular mail should be typed or neatly hand-written on standard 8.5" by 11" or A4 paper. For problem proposals and solutions, please sign each page, and use a new page when beginning a new problem. For email submissions, it would be appreciated if LaTeX could be used, but MS Word, Word Perfect, PDF files, and PostScript are also acceptable. Graphics files should be in epic format or encapsulated PostScript.

Articles

Articles should be carefully written, reasonably short, and expository in nature. When an article is accepted for publication, an author will be send a "Consent to Publish and Transfer of Copyright" form, the return of which, duly completed, is a requirement for publication. Authors will be sent reprints in PDF format, if requested. The Canadian Mathematical Society grants permission to individual readers of this publication to copy articles for their own personal use.

Crux articles should be sent to:

or emailed to: crux-articles@cms.math.ca.

Crux Problems and Solutions

Problem proposals and solutions should be sent to:

or emailed to crux-editors@cms.math.ca.

Each problem proposal should be accompanied by a solution, or at least sufficient information to indicate that a solution is likely to be found. Please include any references or insights that might help the editor. Original problems are especially solicited. However, other interesting problems may be acceptable if they are not too well known and they are accompanied by appropriate references. Ordinarily, if the originator of a problem can be located, the originator's permissions should be obtained before the problem is submitted.
