I'm not sure whether the current replies are enough for you or not, so
here's my comments. Many emacs commands can logically be repeated a
number of times, such as forward-char or maybe self-insert (which types
a character). Others need a number to do something with (such as
set-fill-columns, which needs to know what width to set fill-columns
to).

To pass a prefix argument to such a function, either type C-u or ESC
and then type the number (on the number keys!) then do the shortcut to
the function or M-x function-name. So for example, you might type: C-u
6 0 C-x f

Just in case it helps, you'll then need to wrap the text - try M-q on a
paragraph.
