Missed the x in the last one. The correct answer is 333
First line and number is correct (9)
Second line is correct, but the numbers read 1234 in line 2, but 1224 in line 4. So this isn't 10, it's 9
Third line is correct, but again not the same as line 4, as there are 5 lines above the bulb in line 3 but only 4 lines in line 4. This means line 4 is
9+9x36=333
Nope, keep going
