I only read the first sentence skipped the rest too complicated for me

Then some of the examples of relations from A to B are (i) {(a, b) ∈ A × B: a is the brother of b}, (ii) {(a, b) ∈ A × B: a is the sister of b}, (iii) {(a, b) ∈ A × B: age of a is greater than the age of b}, (iv) {(a, b) ∈ A × B: total marks obtained by an in the final examination is less than the total marks obtained by b in the final examination}, (v) {(a, b) ∈ A × B: life in the same locality as b}. However, abstracting from this, we define mathematically a relation R from A to B as an arbitrary subset of A × B. If (a, b) ∈ R, we say that a is related to b under the relation R and we write as an R b. In general, (a, b) ∈ R, we do not bother whether there is a recognisable connection or link between a and b. As seen in Class XI, functions are special kinds of relations....." ### Inside an Incomplete Novel
