This document gives terse solutions to chap 8 and 17 of the book “Mathematical Circles (Russian experience)” (isbn 8173711151). We thank the authors (Dmitri Fomin, Sergey Genkin, Ilia Itenberg, translator: Mark Saul) for this wonderful book. We hope it helps students who are using this book for self study and instructors who would like to conduct problem sessions.

For the student: Do try problems on your own. If nothing works, look up the solution.
