comment Interesting Property of Numbers in English
There is such a systematic method of naming numbers in English, although the details escape me. Given that a 1000-factor increase in the size of the number results in roughly a 28-35 letter increase in name size ("three hundred and thirty three -illion" and so on) it's clear that the naming convention will never catch up. Consider also what it would take for the size of the name to grow as the number: you'd have to write in unary.

comment Why is $(x+h)^n$ written like this?
Just a note...it isn't necessary to pick an answer immediately. It's usually advisable to wait a day or so to see what people have to say. I'm not saying this because Paul's answer is bad, only because other answers may be better explanations for you.

Sadly, your link to Niven's proof doesn't work.
