  1. u can also take the top horizontal stick from 8, and top right vertical stick from 8, add them to the 7 as a middle horizontal and top left vertical, to say 6+3=9

  2. if you count in hexa, you can solve it by:
    E + 3 = 17
    (since E in hexa is 14)
    or:
    9 + 3 = C
    (since C in hexa is 12)
