1117 = 710 ?

I'm sorry. I know this question is for @Momgie but I can't help. >.< I just want to share my guess.

In 1112 = 25, the first digit of the answer, '2', refers to the last digit of the question, which is '2'. And the last digit, '5', is the sum of the digits of the question, which is 1+1+1+2 = 5. The remaining examples are just like that.

That was just a guess.

Hello ALPHABETAGAMMA, can you show all the digits solving ? it's hard for me to understand. I really appreciate your response, thank you !
Since the last digit of the number 1117 is 7, then the first digit of the answer should be 7. The remaining digit is the sum of all the digits of the number, 1+1+1+7 = 10. So it became 710. Is my point here clear?
