5.1 Is Decision of Difficulty Level in Mathematics “Complex
System”?

If “decision of difficulty level in Mathematics is complex system” is true, it is
right way to use statistical approach. A complex system is commonly understood
as any system consisting of a large number of interacting components (agents,
processes, etc.) whose aggregate activity is non-linear (not derivable from the
