Solve This Math Puzzle (VERY HARD)

In the final sum:

  • The clock value is 9.
  • The calculator sum gives 9.
  • The bulbs contribute 4 lines, with each line valued at 3.

So, the final sum becomes:
9 + 9 x 3(4×3) = 9 + 9 x 12 = 9 + 108.

Doing the multiplication first gives 9 + 324.

Therefore, the correct answer is 333.
