Difficulty Level

If 6 + 4 = 210
9 + 2 = 711
8 + 5 = 313
5 + 2 = 37
7 + 6 = 113
9 + 8 = 117
10 + 6 = 416
15 + 3 = 1218

Then find the missing number in ? + ?? = 123

Split the resulting number "123" into 2 parts - 1 and 23. Those numbers will be 2 results. "1" will be result of "first number minus second number". "23" will be result of "first number plus second number".
So it's easy to see that those 2 numbers will be 12 and 11.
12 - 11 = 1
12 + 11 = 23
Write them together and you get 123.
So the answer is 12 + 11 = 123.
