You can add simple arithmetic to the end of expressions to make them stronger, weaker or to flip them to their opposites. For instance, if you add an expression to Rotation and Pickwhip Opacity, you can then click to the right of the last character of the expression and type +50. The expression will then read Opacity+50. Without the arithmetic, if the Opacity was 100 percent, Rotation would be 100 degrees. With the arithmetic, Rotation will be 150 degrees.

Similarly, you can subtract from an expression by tacking “50 (or some other number) to its end. You can also multiply and divide by typing *50 or /50 at the end of the expression. There are no multiplication and division symbols on computer keyboards, so you have to use an asterisk for multiplication and a forward-slash for division.
