Negative + Negative  =  A Greater Negative Outcome
Positive + Positive = A Greater Positive Outcome

And then we know...
A lesser negative + a greater positive = an in-between-the-two positive
A lesser positive + a greater negative =  an in-between-the-two negative

and a Positive * a Positive = a MUCH greater positive

but... explain how the flipp'n heck this is possible...

Negative * Negative = Positive...
When will a negative, times a negative, equal a positive in this lifetime... when will a positive solution be revealed...
