I am a bit strange when it comes to maths. I hated it at school - back of the class, wasting time - 35% in my final exam.
Now I am doing all the bookwork for our business and love it (especially when everything balances). I am really pedantic, though, it HAS to balance to the last cent, otherwise I worry at it for ages and ages (costs us more in my time that then missing cent, but can't help that).
I do sudokus nearly every day as well - although that isn't really a mathematical pass time. I guess I'm not such a dummy at maths after all.
