If a = b then they [a and b] are equal?
or "identical", right.
For instance 5 = 5, the self relation equality?
Right. The relation "=" only holds "between" one and the same "entity" (object). :-P
In the context of math we might even TRY to DEFINE "=" the following way:
a = b :<-> each and every property which holds for a also holds for b, and vice versa.
