Best ResponseYou've already chosen the best response.1but I don't see how either show a is an integer, maybe i'm missing something.

Best ResponseYou've already chosen the best response.0a 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.

Best ResponseYou've already chosen the best response.1you are saying a is an integer and you need to prove a0 and 0a?

Best ResponseYou've already chosen the best response.0yeah. or show, as the textbook puts it.

Best ResponseYou've already chosen the best response.1well 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.

Best ResponseYou've already chosen the best response.1is this exactly as the book shows the question?

Best ResponseYou've already chosen the best response.1you 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:)
