On the Subject of Double Digits
Wait, why are there two?
This module consists of a large button and two screens showing a digit from 0–9 each.
Take the number of batteries. Use this as the row for the table below.
Then, take the two digits in the display, and use then as the columns for the table below.
Take the numbers at the two intersections, multiply them, then take the least significant digit. This is the final value.
Press the button when the last digit of the timer is equal to this value.
