this is the dumbest question I've ever come up with, but I can't answer it, so that would make me horribly stupid.
Why is:
-1*-1=1
1*1=1
-1*1=-1
1*-1=-1
why can't:
-1*-1=-1
1*1=-1
-1*1=1
1*-1=1
?
Is there any reason why we've defined things in the latter way rather than the former?
p.s. sorry folks, I'm sure there is an obvious and simple reason, but I can't see it right now.
