Who are you, and what is this page about?

     You are a work in progress, as me, as this web page... We are work in progress our entire life...

This is the personal web page of Safet Penjić, PhD. One of the main purposes of this personal web page is to share mathematical problems that I found interesting at various points in my life, as well as a problems that I used in exams or assigned as homework. I have solutions for all of them. :)

On this web page, you can also find an overview of my research :). I hope it will help students discover new and interesting problems during their studies and be useful to both students and teachers, as the page contains a wide range of problems, from simple to challenging.

     I "have" solutions of all problems that are at this this web page -- if you are interested in solutions please write me at
