    I know the method


    7+6 = 113


    the method:

    1. substract two number on the left then you will get the first digit of the answer : 7-6= 1

    2. add up two numbers on the left which is : 7+6 = 13

    3. combine numbers we got from that 2 steps. 1 and 13 -> 113


    so, the question of the riddle is:

    18+13 = ?


    the step

    1. 18-13 = 5

    2. 18+13 = 31

    3. So the answer is 531


    thanks
