Identity property of addition:
\It states that when zero is added to the any number, the sum is the number.
\Property: ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=1ee5a641bd226914a643aad4a9b97acb.png\")
.
Example: and ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8c1c07c8effac878ea5a4f89356e31f7.png\")
.
Verify the options.
\Option A: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=5b4452595d81e8117a11718286d89dfd.png\")
it is satisfied the Multiplicative property of zero, so eliminate the option A. \ \
Option B: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ac76bb97a3b38e5d75505a9cc56199cd.png\")
it is satisfied the associative property of multiplication, so eliminate the option B .
Option C: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9180ef3ffe95ed97e30a2e1c1ab9572b.png\")
it is satisfied the associative property of addition, so eliminate the option C .
Option D: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=394f34ae7b9fbb80afde4ade87aab611.png\")
it is satisfied the Identity property of addition,
Thus, Option D is right choice.
