A number of 50 digits has all its digits equal to 1 except the 26th digit. If the number is divisible by 13, then find the digit in the 26th place.
(In reply to re(5): a little more straightforward
Wait, your right. I guess I was thinking about it all wrong. Without thinking, I must have tried to find a digit where the big number is 13^ a certain integer. I was confusing myself.
