The associative property of addition is a property which allows terms in an addition expression to be "switched around." For example, the addition property says that the following two expressions are equal:

$5 + (4 + 3)$

$(5 + 4) + 3$

Applying this to this problem, we can move the parentheses to cover the 2 + 11 to make a new expression, as shown below:

$2 + (11 + y) = (2 + 11) + y$

A new expression could be (2 + 11) + y.
