Im a 10th grader and i want to learn combinatorics. I donot have a mentor and planning to self study it. Im interested in solving Olympiad probelms and maybe participate as well. I want a book that explains combinatorics to me like a kid!

I know a bit of graph theory and a little bit of generating functions. I would love to learn recurrence relations. I would love to see a book within this topics as well. Thanks!

  • What is your current level? Are you able to solve IMO shortlisted problems or maybe do a good amount of approach? –  Aug 10 '20 at 05:13
  • I can solve 1's and 2's from geometry. Some basic problems from Number Theory. I just started like 2 months ago to solve problems. It's basically long way to go! – Kritesh Dhakal Aug 10 '20 at 05:21
  • @KriteshDhakal perhaps this might help https://math.stackexchange.com/questions/3781790/book-recommendation-olympiad-combinatorics-book . The user who asked this question also is pretty new to combinatorics so the recommendations might be helpful to you .. – Raheel Aug 10 '20 at 07:04
  • @Raheel thanks i will cheeck it! – Kritesh Dhakal Aug 10 '20 at 09:37

I have found Principles of Combinatorics by Chen Chuang Chong quite easy to read and very explicitly presented. It also includes a number of problems from IMO, Putnam and Regional Olympiads.
