## The art of Problem Solving

I've dedicated some room on this site especially for those who
are intrigued by challenging **puzzles** and **riddles**.
Undoubtedly, every person has come along some tough problems.
However, in the eyes of mathematicians and math-enthousiasts,
such hard problems suddenly obtain a beautiful aura when the
solution is either creative, elegant and/or unexpectedly short.
I hope you enjoy some of the puzzles I've listed here, as I did
for sure.

Every **tenth** problem could be considered a challenge, and every title in *italics* is a problem for which I didn't find a solution yet. Care to help me out?
