The problem section of the Nieuw Archief voor Wiskunde is open to everyone; everybody is encouraged to send in solutions and propose problems. Group contributions are welcome.
Note: Problem B in the December issue was not quite correctly formulated. At the link below you will find the correct version.
For each problem, the most elegant correct solution will be rewarded with a book token worth € 20. At times there will be a Star Problem, to which the proposer does not know any solution. For the first correct solution sent in within one year there is a prize of € 100.
When proposing a problem, please either include a complete solution or indicate that it is intended as a Star Problem.
