Memory Pi game

Memory Pi is a game I created for fun on Pi Day (14th March) and which consists of quickly typing as many digits of π as possible.
The European School of Strasbourg uses it to organize contests every Pi Day since 2019:
Pi Day 2022
Pi Day 2021
Pi Day 2020
Pi Day 2019


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.
