I'm really curious what people who are good at math are actually doing. I presume my thinking methodologies are just so far removed from how they think that I'm unable to imagine it, I can hardly even visualize a number never mind manipulate them, it's strange. I couldn't tell time till I was in my early teens, and even then it was a lot of work, and even today I wouldn't exactly call it "automatic".
