a is an integer is a condition. i just need to prove it or sth. my textbook is very subtle about requiring wat form of proof.

well part 1 makes no sense because 0 is in integer and 0 does not divide 0, and the second part makes no sense because nothing divides 0. So you can't prove either.

you can say, if a is an integer and a is not 0, then 0=K*a when k=0, so a0 because k is an integer (by definition of ab), for part two nothing divides 0 is your counterexample:)
