SAME seems corresponding to CONNECTED, and DIFFERENT seems corresponding to DISCONNECTED.
Different – disconnected
Same – connected
RELATIONS –
If 2 things are same, they are obviously connected to each other.
If 2 things are connected to each other, they have a similarity in them.
If 2 things are different, they may or may not be connected to each other.
If 2 things are disconnected from each other, they are different from each other / bear no similarity between them.
******************
ADD seems corresponding to TOGETHER, and SUBTRACT seems corresponding to APART.
Add – together
Subtract – Apart
RELATIONS –
If 2 things are added, they are together.
If 2 things are together, they are not necessarily added.
If a thing is subtracted from another thing, the 2 things are apart.
If 2 things are apart, it is not necessary that one has been subtracted from the other.
********************
With regard to relationships, do you see a similarity between the following two statements?
1) That, in a one way relationship, A => B but B not necessarily => A. But B is an effect of A.
2) That, (a-b) is not necessarily (b-a). But (b-a) = -(a-b).
