But I don't know how to _solve problems_ with it.

Do you have problems? Maybe you just don't to solve anything at the moment.

This is stupid on so many levels. What about floors? 3m x 3m in a skyscraper can be an address of thousands of people. And why even allow the oceans?

I know that 'fn' defines a function. It could be 'def', 'funct' or 'Ξ', it doesn't really matter.

Also, what's the problem with pronouncing 'fn' as 'ef-en'?

You are not supposed to read programs aloud. What do you think it is, poetry? 'fn' is a symbol.
