I needed to use a negative number to get 0. I also needed a pair of values that add to 15. To get both odd and even answers to need odd and even numbers, since
odd + odd = even
odd + even = odd
Once I had -1, 10 and 15, I used trial and improvement to find the other two numbers
Solution: -1, 1 , 3, 5 and 10
