Maths for funny

That day, I made a phone call to my friends. When I finished this, I remembered a thing what I did last week. It was discover of myself. Most of people have has own hand-phone number. Let me tell you this interesting thing that create by myself.
If the hand-phone number is ABCDEFGH
Firstly, I use my first 4number ABCD, times 80 (1)
Then you add 1 (2)
Then you use this total number times 250 (3)
Next, you add your last 4 number EFGH, add them to the total number. (4)
Then, you do the step4 again. (5)
Finally, you minus 125.and let the total number divided by 2 (6)
Now, can you see the number on your calculator, is it the number of your hand-phone number. Is it just like a magic? Am I clever of finding this clue? I think I can be the scientist or the maths teacher.
I think everybody can find the magic of the numbers. If you bear your mind in it, also can find. Just like I can find what is the thing in the poker King and Queen’s hand. Am I right?
