Multiplying Negative Numbers

May 26, 2005

Cool illustration: Consider good guys as positive (+) and bad guys as negative (-). Also consider entering the room as positive (+) and leaving the room as negative (-). Thus

Good guys (+) entering the room (+) ==> positive
Good guys (+) leaving the room (-) ==> negative

Bad guys (-) entering the room (+) ==> negative
Bad guys (-) leaving the room (-) ==> positive
