    5*5=25, 2+5=7, 7-5=2
    6*6=36, 3+6=9, 9-6=3
    ..
    9*9=81, 8+1=9, 9-9=0
    similarly, 10*10=100, 1+0+0=1, 1-10=-9

    Avoid posting Answers please. There is no point in even trying to solve the riddle then. The person posting took some efforts in finding that riddle. Respect that.

    PS: Answer is -9. I got that too.
