Memory Pi game

Memory Pi is a game I created for fun on Pi Day and which consists of quickly typing as many digits of π as possible.
I was happy to learn that the European School of Strasbourg uses it to organize contests:
• Pi Day 2021 - European School of Strasbourg
• Pi Day 2020 - European School of Strasbourg
• Pi Day 2019 - European School of Strasbourg

The American Mathematical Monthly

The American Mathematical Monthly is a journal in which university researchers post problems and challenge the readers to solve them. I am citing here some problems that I solved during my studies before starting my thesis which turned out to be challenging enough.
