Sure there can.
In *this* universe...
1+1=10
7+1=10
9+7=10
9+8=10
...can all be true, but you'd argue that they can't - and that they'd violate identity - and you'd be wrong, because of your myopic view.
Identity means that something is itself. 2+2=4 because 2 things and 2 things is the same as 4 things. That is completely unlike the sums you described which aren't even proper sums because they DO violate identity.
Quote:Similarly, 2+2=4 can be false - and violate identity - in *this* universe.
Like I said, the universe is irrelevant. Tell me why other universes are remotely relevant to A=A.
When you're saying "2+2=4 can be false" you're saying "A=A can be false." No it can't. Adding "in other universes" on the end of it won't get you anywhere. If we're talking about A we're talking about A, regardless of the universe.
