I'll have to agree with the others, some people's brains work differently. It's a very long story, but I'm 13 and a junior in high school, as I skipped three grades. I go to a normal high school and take normal classes but take an AP (advanced placement) calculus math course. I really enjoy math and it comes easy to me. But it doesn't for everyone. I'll be done with all the math offered at my school and probably will be going and doing a PSEO for math next year. However, even though I'm good at math doesn't mean I'm good in all my other classes. I may get A's and B's, but I struggle immensely with classes like American Literature and even US History. Having a good teacher really, really helps so if you're teacher is good, I'd try asking him/her for help. If that's not an option, I would recommend getting a tutor. I am blessed with a great math teacher who is completely willing to help kids that have trouble with math. However, we do have a really, really bad math teacher who teaches Algebra 1, Geometry, and some other classes. I've been fortunate enough not to have him.
Good luck though! And you also must take this piece of advice, and that is that when you're learning algebra at first, it can be extremely challenging. However, stuff will start to make way more sense once you get the basics down, so I promise you it will get better. Keep it up though, and don't stop trying if you don't get a concept, that's what I do!
