I would actually prefer that label early on. I learned from my parents that back in preschool and early primary school i was math genius. Supposedly i astonished the ones administering preschool tests by doing stuff from two grades above effortlessly.

Sadly later on I was stripped of my potential by math teacher in primary school. I solved all exercises by writing the result outright, and she forced me to write down every. single. step.

I got so used to that over course of 3 years, that now I'm slower than average at mental calculations. i cannot do algebra efficiently without a piece of paper anymore.

That teacher is probably the only person in my life i genuinely hate.

I have a PhD in maths. Writing down every step is the only way to get things right and be able to verify that (essential for anything that actually matters). The best maths advice I ever got was a high school teacher (not even my teacher) looking at my work and telling me to write down more steps; suddenly my accuracy and speed got way better.

Maths ability varies widely, and I don't think being able to do things a couple of years earlier than your peers is that uncommon or really predicts your later achievements, except for the encouragement of early praise pushing you in that direction.

If you really want to be good at mental calculations, practice that. You haven't lost anything you can't regain. However, pen and paper is more accurate, more permanent, and can often be faster, though it feels slower because you're physically moving a lot. Your hatred is beyond futile, achieving nothing but hurting you and holding you back.

Different people need different advice.

I love solving problems and am very good at it but writing things down makes me hate maths, the act of moving the pen is much more effort than the problem itself. I used to stump my professors by solving the problems they were explaining in my head long before they would have gotten to a solution. But then I got diagnosed with ADD after I completed my masters, I can write down things no problem when I'm on medication, but if people forced me to write down everything in school when I were undiagnosed I likely would have dropped out of middle-school and maybe even committed suicide. Several of my siblings dropped out of middle school so that is not an exaggeration.

I don't think that not writing things down held me back, I think it forced me to become creative and learn things properly since I couldn't just follow algorithms blindly like my classmates. So maybe I should be grateful that I was diagnosed late and thus forced to invent my own maths throughout college. I likely would have gotten perfect grades with medication, but I'm pretty sure the things I learned and the intuition I built are way more valuable than grades.

But if someone like you came around and thought I did things wrong then you would have ruined my life. Please don't force that on someone else and when they inevitably fail you just say something like "I guess he wasn't that good after all, nothing I could've done!".
