Problem
The value of 
is
Solution 1
We can use order of operations to evaluate the expression:

Solution 2
We can subtract 
from each answer choice, and see if the result is divisible by 
(which works because plus a multiple of is what we are looking for in the problem:
, which is not a multiple of
, which is not a multiple of
, which is a multiple of
, which is not a multiple of
, which is not a multiple of
The only answer choice that is more than a multiple of is
