I was considered bad at maths a long time ago, barely passed calculus in college. 20 years later, I wrote Geometry for Programmers.
Maths is a lot of things. Meticulous symbol crunching is one of them. I'm not good at that specific part, I'm constantly ending up with the wrong sign or losing variables doing even the simplest algebra. Luckily, maths is the other things too. For one, I get kicks from inventing things, and maths gives plenty of opportunity for that. I enjoy solving problems, I like experimenting, and there is a lot of that in maths too.
As for the symbolic computations, I acknowledge that there are people who enjoy them too, I'm just not one of these people, so I use a computer-aided algebra system. Makes math fun again: https://wordsandbuttons.online/sympy_makes_math_fun_again.ht...
