Homework Equations
The permutation & combinations equation? I don't quite know how to type them out in here, but there's the calculator :rofl:
The Attempt at a Solution
Since the maximum number of integers a value can have would up up to 1000000000, there would a total of 1digit+2digit + 3digit+...+8digit numbers +9 digit numbers altogether. 10 digit numbers don't count as the last number would be 0.
For the 9 digit nos, it would be just 123456789 which is 1 way, 8 digit: 12345678 or 23456789, but as the digits get smaller I'm confused and at a loss to what to do.
Any help would be greatly appreciated.
