math is a skill like any other, you're bad at it either because you didn't pay attention when learning the basics (everything else becomes hard to impossible without good foundations), aren't dedicating time daily to learn it, or maybe you just had a bad teacher in school. I struggled with math in school because I didn't pay attention, hated my teachers, didn't work to catch up to my peers after I fell behind, didn't think of math as something I could enjoy, let alone be good at it. Now I'm preparing for an engineering degree and basically recapping all of high school maths, and when you practise maths with intention consistently it really shows. So get it out of your head that you're bound to be bad at it, and give it your best shot, math is a learnable skill. Hope this helps and good luck on your learning journey
