12. The following exercises contain definitions or results from more advanced mathematics courses. Even though we may not understand all of the terms involved, it is still possible to recognize the structure of the given statements and write a meaningful negation of that statement. (a) In abstract algebra, an operation * on a set A is called a commutative operation provided that for all x, y e A, x * y = y * x. Carefully explain what it means to say that an operation * on a set A is not a commutative operation.
