Steps 1 to 25: submit your answers every week
Every week, find the problem:
– in the Sciences et médecine supplement of the Wednesday edition of Le Monde,
– on the website **www.affairedelogique.com** between Wednesday and the following Monday.
Look for the problem and submit your answer on the website **www.affairedelogique.com**
– To do so, log in (you must register first, if you haven't already).
– Fill in the boxes for each of the problem's questions.
– You can change your answer right up until the last moment.
– You can skip a step if you don't know how to solve a problem.
