The Mystery Writer's Gambit

The Mystery Writer's Gambit (, Zoku - Misuteri Sakka Kara no Chōsenjō, Lit. "Continued - The Mystery Writer's Written Challenge") is the 9th side case in Judgment.
==Plot==
Takayuki Yagami once again meets the Cloudy Sky owner at Café Mijore. As with the previous side case, they are back in the conference room to try and unlock the safe to win the rights to the second book by the writer.
This time, the answer to the puzzle is based on the number of digits of the answer to the sum. For example 111x2=222, so the resulting number is 3. Following this logic through the four puzzle equations results in:
*111x3 = 3
*12x99 = 4
*333x0 = 1
*5x6 = 2
Thus, the combination is 3412. When Yagami enters this combination, he once again unlocks the safe and wins the rights for Cloudy Sky.
