Answer: 0
Explanation:
100+0=100.
Just basic addition too. 100+0=100. That simple.
No other number can give off 100 like 0 can. 100 plus 0 just gives it the number itself.
Just like how 6+0=6. 6 is just being added to itself.
So, your answer for this is 0. No other number can give off a better answer than the 0 for this problem.
