Basic Quotients

    Hi All:

    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.
