On the afternoon of February 24, 65438, how did the five-digit mind-guessing magic performed in the whimsical program of Children's Channel change?

(1) Ask the other party to write a five-digit number casually (all five digits are not the same)

(2) Use these five numbers to form another five numbers at will.

(3) Subtract two five-digit numbers (reduce large numbers).

(4) Let the other person think of any number and tell you other numbers (except the one that the other person thinks of).

5. The performer only needs to add the number spoken by the other person to one digit and subtract 9 to know what the other person is thinking.
