Maël COURTAIN, 13 years old, born in 2007, near Paris, France. I like mathematics at school and I am a geek of logic and mumeric's games. Later, I hope to become an engineer as well as my uncle Julien COURTIES. He teaches me Python and I think it's very fun to get problem solving with a computer. Maybe, we will find more results together later, after my first steps about the multiplicative persistence !
