Hi All:(adsbygoogle = window.adsbygoogle || []).push({});

We know that the quotient ## \mathbb Z /2\mathbb Z ## ~ ## \mathbb Z/2 ## . Is there a nice

way of computing the quotient : ## [\mathbb Z(+) \mathbb Z ]/[ 2\mathbb Z(+)2\mathbb Z]##

I know the long way, but I wonder if there is a nicer, shorter way to do it.

Thanks.
