Chessmaster1000: Repetion is the key to redundancy!
I'm not sure where you're from, but around here the "+" sign and the word "and" mean almost exactly the same thing. As I wouldn't write the word "and" or use the "+" sign if I was to write it on paper, I suppose I could've just put 33 1/3 cm. I wanted to avoid confusion, but apparently you got confused. Oh well. Writing numbers and how they are spoken look different.
So I'll say it like this next time.
Thirty-three and one third centimeters. How's that?
