Hi all, I'm planning to do a stream this weekend (edit: now in the past), focusing on problems in Number Theory.

I've put together a mashup of 12 problems (ordered by difficulty), which is available here: https://codeforces.com/contestInvitation/8305134301b2607eaa233fc638ac5fbf91a5c82e (thanks jschnei and neal for problem suggestions and feedback).

Try to solve them on your own! We'll go over those problems & their solutions on stream. Also, feel free to suggest any other number theory problems or concepts you'd be interested in, and I'll try to take a look on stream.

My stream can be found in the sidebar, and you can also follow me directly on Twitch. I upload my streams (afterwards) to YouTube as well, so feel free to subscribe there if you'd like to watch them later!

Edit: I've published this (with timestamps) on YouTube: https://youtu.be/VoD5Mt3Bdec
