Problèmes:
Question à résoudre par des méthodes rationnelles ou scientifiques.
We will post in this part questions which are more linked to math.
To find the solutions, the attendees will be more keen to use math technics, particularly if they want to explain their solutions.
Once more, we will insist on the fact that finding a solution to a problem, is to be sure that the solution is correct and that we have all the solutions.
Difficulties are uneven.
As for the enigma, attendees must not hesitate to send me a problem they found nor to send me their solutions.
After revisions, they will be post too.
Good luck.
