My question is just to ask whether the operations like:-(adsbygoogle = window.adsbygoogle || []).push({});

AUB is a relation or not?

in our book it is written that the relations of two sets should be subset of the cartesian product of two sets but i think that relations are those which connects two sets and that can be AUB(A union B) also,because it connects two sets either.

so,i want to ask whether AUB can be said as a relation or not between A and B sets
