I live in Mexico city. However, I am not so interested in whether these exist in my vicinity but want to learn if they exist, if they do then It might be easier to make them more popular in other places.
Are there mathematical competitions for adults? I have been into a couple of mathematical competitions and they are fun. However, its sort of a race against the clock because you only have a couple of chances until you are too old. Are there mathematical competitions for people of all ages. I have looked this up but found none. It makes sense to separate people from second grade and 7th grade. But: for example in sports once it comes to adults they separate them in different leagues. This could work to make it fair for mathematicians and mathematics enthusiasts alike.
Thanks for your answer.
PS When I say adults I mean people who need not still be studying in college, it includes people who have regular jobs.
