Some people just don't get math. Me personally, I am a math major and I am bipolar. I love math, it is one of the few things in the universe that makes sense to me. My step-daughter however, is just like you were. I try to explain it to her and she asks me if I'm speaking Chinese. I just try to use terms and examples that she can relate to to make her understand it.

Another thing, it is proven that women tend to do worse in math than men (the whole left side right side brain patterns thing).
