Are people who are good at math born with high IQ or the result of being guided as children?
I think good math has something to do with people's natural IQ and being guided when they were young. I prefer the former because everyone's IQ is different. I had a child in high school who didn't study very much, but he was the first in the exam. Before, I thought he was stealing lessons at home, but later I found out that he just attended classes and listened occasionally. However, there is another friend who studies hard every day, but still.
