beatiful of mathematics

math is so beautiful
Believe do not believe I can guess your thoughts. Let's play briefly with math. you hope you are the people who like math, even if do not like you expect after this game you become like the math. This is our game!
I ask you to choose three different digits between 0-9. Then arrange the figures so that it becomes a numbers with hundreds, tens and units. Suppose the order ABC.

Then your next task is to reverse the order number from the first. If you had the sequence ABC is now the CBA. After that look for the difference. Note: The difference is always positive because the difference is less the result of the reduction of large numbers of small numbers.
From here note the difference. Assuming the composition of the score as XYZ. If it only consists of two figures tally the difference then give the number 0 (zero) in front of him. If it's behind you now the order of the numbers become Zyx.
Well because in the beginning we do the subtraction, then in this second stage we perform the sum. Now you add the results of XYZ + ZXY.
If so then I can guess and make sure your answer is: 1089
How, really magical is not it?! With the help of mathematics turns out I can guess the contents of your mind.

It turns out there's more miraculous things than math. Here goes some of that magic:

Try Consider these figures!
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98 765
123456 x 8 + 6 = 987 654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987 654 321

It's amazing regularity these figures. Anyway if you do not believe should be checked with a computer or calculator or abacus or a pebble or a stick, and improvise.

We'll see more examples!
1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11 111
12345 x 9 + 6 = 111 111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111 111 111
123456789 x 9 + 10 = 1111111111

The results are fantastic of course!
One more example of that is not less amazing. Here goes:
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12 321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111 111 x 111 111 = 12,345,654,321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321
