I guess it's a good thing you managed to get out of Iran.
What educational level do you consider the math questions? Would they be on a Masters level? I would think the problems would be above BA levels but how much higher? Or am I totally wrong about that?
How many math categories were represented by the questions?
How well would the average maths Phd have done on those questions? would you expect those Phd's to also ace the problems?
The post that was quoted here has been removedYou neglect an important cultural aspect, relating to how likely people are to be interested in competing in the Olympiad. For example, I went to a MIT-level university that had more open places than applicants; my application was a formality. I was never under pressure to compete with other students or engage in extracurricular activities (such as these sort of competitions) in order to distinguish myself from other students. Hence, in Dutch culture these kind of competitions simply aren't as popular. So these results should not (only) be interpreted as a gauge of the level of mathematics education or the likelihood that someone from a certain "culture" is interested in mathematics.

Before boasting of alleged grad-school math prowess, please provide specific qualifying credentials. Otherwise, your opinion will be given the consideration and seriousness normally reserved for a profit-driven trade school.

I could tell you that I am an academic with a PhD in theoretical quantum physics. Or that could be made up in order to impress some senile Americans. One can never be sure these days.

I'm American and I'm impressed. 🙂

The post that was quoted here has been removedI would guess it's something to do with common factors. 21n/14n where n is a natural number will always have common factors 7 and n. However, 4 and 3 have no common factors other than 1, which doesn't count for the purposes of simplification. I think that adding 4 and 3 to the numerator and denominator respectively of a fraction that is already simplifiable means that it can no longer be simplified, as 4 and 3 have no common factor.
