Me and my buddy got the answer. How we got the first answer is I asked my buddy to solve the problem beginning with the numbers 2, 2, 2 and 2 and he said the answer was 16. So, we tried adding 2, 2, 2 and 1 and it finally made 15! When we tried to find another solution, I had an idea. Instead of adding it up from the 4 circles, we can just break it up from 15 (work backwards, starting at the top of the pyramid)!!
