Mobius Inversion and Multiplicative functions : Tutorial

I prepared a tutorial on Mobius Inversion and multiplicative functions, with some problems.

I tried to make it as such that it doesn’t need any prerequisite about the mathematics involved behind it.

Slides

Slides are also attached in description if you prefer reading through text, than watching a video.

Since, this is my first video, ignore the mumbling and any constructive criticism are welcome.

PS : I shared this on codeforces yesterday, but since most of Indian community is not on codeforces, so I am sharing this here too :slight_smile:
