I am still 15 years old, but I am very interested in pure math. I have been teaching myself though books, from the internet and from others for the past year or so. I haven't mastered all the topics that are covered in university, just the ones that happen to interest me (elements of differential and integral calculus, complex analysis, etc. You can see what I am interested in by looking at the questions I've asked and answered).
Now, a few months ago, back in school, I asked my math teacher for help on a differential calculus question whose solution I did not understand. I was told by this teacher that I should not be doing calculus and I should wait until I learn it in school. Other math teachers either did not understand what I was asking or shared the same view as my math teacher. For awhile this had distressed me very much, because some of my own math teachers were telling me to stop learning math and to wait three or four years to continue! Should I stop learning math by myself? I decided that I would keep going, because this is a hobby and interest of mine and I didn't think teachers should have the right to stop me from learning.
I find it more and more difficult to proceed learning on my own without a mentor who can and will help me, and I don't know what to do. I went to my school's math club, but alas, no one there was that interested in doing math for fun like me, and no one was interested in answering or helping me with my questions. This website has proven very helpful to me, however, it is not like talking ans asking a person face-to-face.
What should I do? Am I learning math too early? Should I wait until university to continue learning calculus? If not, how should I get a teacher or continue to learn on my own?
