 ```
 
 When ``!exp`` is used, the first argument (the first piece of text after the command ending with a space or a newline) is passed into the formula ``n^2``, which is then passed to the ``/calculate`` command.

+***
+_Note:_ If you're using a string as a single argument and it contains spaces, you should quote the string when passing the argument, like so (assuming `/alias !echo "/speak You said: $1"`)
+``` 
+!echo "This is a string with spaces as a single argument"
+```
+This isn't needed with `...` syntax because it passes all available arguments.
