need help with homework

Hi All,

I need to find the missing number in the attached image. The numbers combine in the same way to make correct arithmetic statements.

Any help will be greatly appreciated.

That sum is 10 in the first example, 9 in the second, 13 in the third, and (assuming the same rule applies) 17 in the final illustration, which implies the missing number is 14.
