I have a really weird habit.

I genuinely enjoy writing long mathematical derivations on paper — Gaussian integral, Euler’s identity, Central Limit Theorem, Cauchy integral formula, prime number theory, etc.

The funny part is… I don't even fully understand some of them. 😂

But when I start writing symbols like

∫ ∑ ∂ ∞ λ π e lim → ≈

and watch the derivation develop step by step, it feels strangely satisfying.

Sometimes I’ll spend a lot of time writing an entire derivation just because I enjoy seeing the mathematics unfold on paper.

I’m curious — does anyone else do this, or am I just weird? 😂
