I am in discrete math class right now and trying to get the sets of numbers straight.(adsbygoogle = window.adsbygoogle || []).push({});

So, does the set of integers include 0? Is it ok to use 0 in proofs, that makes finding a counter-example a lot easier and disprove a statement about all integers.

Was just wondering if that is legal..... feedback on this is very much needed
