METHOD
I tried to get the higher values inside the result box. I chose 7 out of 7 and 8. And then, got the following things working -
8-1 = 7
8-2 = 6(Next big number)
5-1 = 4(Next big number)
5-2 = 3(Final big number)
ADDITION
A=8

METHOD
For addition, I tried getting the smallerbigger numbers in the result box.
6+2 = 8(Biggest)
6+1 = 7(Next biggest)
3+2 = 5(Next biggest)
3+1 = 4(Final)
