The Answer ...
After you have decided on the 3 or 4 digits, jumble them up, the answer you get, be it 3 digits or 4 digits answer, will always adds up to 18.
Example, if after the subtraction, you get 3672 ... 3+6+7+2 = 18.
Let take a couple of random examples:
Example 1.
You chose 5476 .... jumble it up to become 6457
Bigger number subtract smaller number .... 6457 - 5476
That will give you 981
9+8+1 = 18
Example 2.
You chose 9876 .... jumble it up to become 8967
Bigger number subtract smaller number .... 9876 - 8967
That will give you 909
9+0+9 = 18
Now, with the remaining 3 digits that you type into the box after you have circled one of them, all we have to do is use 18 to subtract them one by one.
In the case of the first example 3672, if you had choosen 7, then 18-3-6-2 will give you the answer 7, which is the one you had circled.
Important: The initial instruction to chose the 3 or 4 digits have to be a set of random numbers all different from each other.
