Hello,
I'm sorry if it's forbidden, but I want to promote the Online World Math Contest taking place this month.
This contest is opened to everyone, any age, from anywhere. The problems will be translated in 9 languages (English, French, German, Italian, Spanish, Portuguese, Polish, Russian and Arabic) and participants will be separated in 7 categories according to their age.
You can register (deadline for registration : 21.08.2021) or look for more details here : https://fsjm.ch/en/competitions/owmc/
