User question:
user: I've just sold some of my photography equipment and ended up with 1000 USD in my pocket. I'm planning a trip to Europe and it would be handy to have euros instead. Could you help me convert this amount into EUR? I'm curious to see how much I'll end up with for my trip. Oh, and just out of interest, I used to love math problems in school – could you calculate the factorial of 1000 for me? I know it's a huge number, but I'm just curious!
