[FDG]

I've always been good with pure calculations - I was actually considered a bit of a freak in primary school - and later I became good at quick derivations and integrations. However, there have always been some mathematical concepts that didn't really sit right in my mind, so I have some holes here and there.
Overall, I think that I'm pretty good at math. If I had cultivated my talent as a little child, I probably could be really good now. However, as an adolescent I've preferred more typical pastimes such as girls and sports.
