Looking for a bit of tips and feedback

I am building a Matyhs only rack. I want to see how far I can get with a case with only (mostly?) Maths in it.

Looking for:
* creative ways to patch Maths(es)
* your experience (or things you have seen) in using Maths creatively
* how far you think a system like this can go (and whether only Maths is feasible)

Thx people!
