If I can guess your number that you end with, I might be Einstein.
Choose a number between 1 and 10. Multiply your number by ten, and then divide the number that you have now by the number you chose at the start. Now, subtract 3, and if I'm not mistaken, your number now is 7.

+37101 What you are describing is simply this:
10(x) / x - 3 which is ALWAYS just 10-3 = 7 for ANY 'x'
