You answered your own question. Fractals.

Series.

Ancient Greek geometry.

Planar geometry was mentioned above. Essentially very similar.

much of number theory, actually

Really this. Only the most retarded of brainlets can't do simple calculus like derivatives or sigma notation.

Analytic/Non-Eucidean Geometry

Yeah this too. Planer Geometry is good.

I personally like just standard Vector Calculus, if you want to speak about something complex but meaningful, due to its applications in science.

Basic Group Theory

algebraic topology

>>8647140
All of it. What's interesting is usually what is challenging, so it changes as you advance.

>>8647140
the mathematics of fucking killing yourself you pitiful brainlet

you won't be able to understand shit if you dont have what it takes

>>8647140
Hodge conjecture

f(x)=a-x^2

Basic set theory

>>8647140
If it's interesting its easy to understand by definition, you just need to know where to start.
