Hello as title, any math topic suggestions that have few resources on, and are not too hard (i.e. it's explainable in one blog, perhaps with high-school maths knowledge)? IMO my previous blogs on maths (lagrange interpolation and linear modulo inversions) are pretty pog and received decent feedback, and I think (not to boast or anything) I am a good explainer? So I want to contribute with my grade 10 maths knowledge and also practice my english and writing skills in general.

It's free too for the lazy people out there, so you save your time and get your credit while I get my contribution points. Win-win condition (win for the cf readers too).

tldr please read blog title and reply thx
