- Arithmetic using numbers in equation form?

Hi everyone.

I haven't been here in years, I'm surprised the account still works.

Anyway. I have a mathematic thought/question that I really want to learn about. I realize this isn't going to be the easiest thing to explain if it is even possible, so please forgive me.

So, What I want to do is be able to extract a specific digit from a number when that number is stored in some formulaic form.

An easy example: 111^2, digit 1(leftmost, 10,000s column, whatever) = 1. digit 3 = 3, digit 4 = 2 etc.

A more understandable example is the number 2^(82589933) - 1 which is one of the largest known primes.

My computer will never be able to process that number as a standard number, so I'd love to be able to do arithmetic on it while it's in this more easily maneuvered form.

ultimately, in this case, I'd love to be able to incorporate this methodology into an iterative function that prints the number one digit at a time so as to not attempt to choke on it's sizeable girth.

I do remember hearing about something like this being used with Pi, but I do realize that's not necessarily related to the field I'm asking about.I hope that makes sense. Thanks for any advice anyone can give.
