- Find the leftmost position where at that position the digit of number A is equal to number B. Remove all digits to the left of that position from number A. If there is no such position, then you don’t remove any digits from A.

- Multiply number A and number C, rounding down. Enter this number into the display by using the keypad below and pressing the green button labeled S.
- The number entered will become the new displayed number, however the colors for it will be randomized.
- Keep doing the steps above until you reach 0. When 0 is submitted, the module will be solved.
