Previously ,
let's say you 're filling a magic show and plays it in front of the audience.

The steps
are:

1 ) Write
down number 1089 on a piece of paper, then save / hide the paper, do not let
the audience see the numbers you wrote earlier .

2) Ask one
of the audience to write 3 digit numbers (on paper), the rules of
"Difference in the first digit and the last digit must be at least 2 (eg
153, 294, 486, 654 ..". While the person is writing, close your eyes so as if
you are a real magician until the person is finished writing.

3) With the
position of your eyes still closed, permit the person to write down that number
with the digits reversed from right to left.

Example: If
the audience choose the numbers 654, then he should write the number 456.

4) Setelah
itu, minta orang itu untuk mengurangi kedua angka tersebut (angka besar - angka
kecil).

Contoh: 654
- 456 = 198.

5) If you
have obtained the results, ask _ him to reverse the numbers.

Example: 198
becomes 891.

6) ask him
to add new numbers to the numbers that have been reversed. The results of this
sum is the end result that you will show.

Example: 198
+ 891 = 1089.

7) The last
step, open your eyes, and show the the audience numbers you write on a piece of
paper, and the audience will be surprised.

The number
you wrote the first time will be the same with the end result that was written
by the audience.

Good Luck!
