R. Hansen says:   I was thinking... (3) * (2) = (2) + (2) + (2) = 2  2  2 Or the other way around ... (2) * (3) =  3  3 (repeated subtraction) (I just realized so much for crabtree's subtracted once from itself theory, that was an unexpected bonus) And with two negatives... (2) * (3) =  (3)  (3) (thus, when you are subtracting a minus you are actually adding)  
That's kind of cute  I like it. But I think to make it solid you would have to define multiplication of (+)x() and ()x(+) first, and treat them asymmetrically!
