Numbers are infinately manipulatable.
Using factoring, you'll see you are multiplying our first three digits by 10000 (putting them in their proper place) then having us put in our last 4 digits.
It seems to me that it would've been quicker just to type my number into the calculator to start than go through those motions...I don't often multiply by 4, add 8, divide by 4 then subtract 2 when coming up with a number.
To each their own.
Wow Skido. Thank you for opening my eyes to how this works. I thought it was magic... you mean it's just a slight of numbers meant to amuse?
