.
Adding 0 to a number doesn’t change the result.
\It preserves the identity of the number.
\This illustrates the Identity Property of Addition (![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=407e45279b665d90841e082d419c0af9.png\")
) and
0 is called the additive identity.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
