Do I have to be good at math to be a developer?
It all depends on the type of company that you target behind your learning. If you plan to enter a spaceship constructor company...sure, if not you just need to practice logicals, puzzle solving. I'm myself bad in mathematics but I'm developper for many many years now and I can do it without mathematics problem.
