Description: Choose between 1 and 9998 two different numbers, they contain exactly the same number (except 0), such as 1000 and 1,1234 and 4231. With large numbers of them, minus the decimal to get the result R. R removed from the result of a non-zero number. If the remaining number of digits less than 3, the first fill 0, making it at least three digits. Can be shown that if given the remaining three figures, then, can determine that the figure was removed.
Such as:
Given numbers: "087", can confirm the figures were removed 3. For 4321-1234 = 3087, removed 3, and the remaining 087.
Given numbers: "099", can confirm the figures were removed 9. As 1000-1 = 999, 9 removed, leaving 099.
