I’m practicing competitive programming, but maths and especially combinatorics are my weak points. I’m okay with implementation and standard logic, but I struggle with counting problems, combinatorial observations, and math based reasoning.

I want to improve maths/combinatorics only from a CP perspective focusing on patterns, intuition, and common techniques rather than heavy theory or memorization.

I’d appreciate advice on:

**Where to start if maths basics are weak**
 **Which maths/combinatorics topics matter most for CP (priority-wise)**
 **Any beginner-friendly resources (blogs, books, playlists, CF problem sets)**

If anyone here had similar issues earlier and managed to improve, please share what worked for you.
