I am a 13 year old boy from Hong Kong, My dad is a math teacher which probably accounts for SOME of my interest in math. I am really interested in math. I self-taught myself (with little help form my dad when I needed help) Trigonometry, Differential and Integral Calculus (well most of it), Solid of a revolution, Taylor and Maclaurin series, and recently I have been learning some set theory.
I have a feeling that the things I learn are going all over the place, I just learn what i find interesting, and sometimes I don't understand some topics because I don't know some previous topics so I will need to go back to learn them. Should there be some order with what to learn first and what is the order?
Thanks in advance
