You can prefix a command, or  a single key press with the universal argument
C-u :

,----[ C-h k C-u ]
| C-u runs the command universal-argument
|    which is an interactive compiled Lisp function in `simple'.
| It is bound to C-u.
| (universal-argument)
| Begin a numeric argument for the following command.
| Digits or minus sign following C-u make up the numeric argument.
| C-u following the digits or minus sign ends the argument.
| C-u without digits or minus sign provides 4 as argument.
| Repeating C-u without digits or minus sign
|  multiplies the argument by 4 each time.
| For some commands, just C-u by itself serves as a flag
| which is different in effect from any particular numeric argument.
| These commands include C-@ and M-x start-kbd-macro.
| [back]

For example : C-u 25 . gives 25 dots : .........................
