Problem
Aaliyah rolls two standard 6-sided dice. She notices that the product of the two numbers rolled is a multiple of 
. Which of the following integers cannot be the sum of the two numbers?
Solution 1
First, figure out all pairs of numbers whose product is 6. Then, using the process of elimination, we can find the following:
is possible: 
is possible: 
is possible: 
is possible: 
The only integer that cannot be the sum is 
.
