Hello everyone. My name is Keivan Mirzaei and I am a math student. This is a personal website with the intention of promoting and introducing math problems to a wide range of students and math enthusiasts. It is a fun activity of mine as I usually spend my free hours on thinking to math problems.

As a warm-up you can show that if the points of the plane are each colored **red** or **green**, then one of these colors contains pairs of points at every mutual distance.

You might be interested in evaluating

\[ \sqrt{1+2\sqrt{1+3\sqrt{1+4\sqrt{1+\dots}}}} \]

or showing that at every party always two people have the same number of friends present.

Please feel free to contact me through my email `keivan.mirzaei at outlook.com`

for suggesting interesting problems.
