Without resorting to a RichTextBox and applying formatting
How would I do this with the richtextbox?

if it was a variable number you might want to set up some kind of generalised function.
I would like this to be for any number not just one through ten.

Your only problem then is to find a font that supports those characters, or you get little boxes instead of your subscripts.
Yes I am getting little boxes. Even with arial unicode ms font which supposedly supports it.
