Sum To 2007 Nines? (Posted on 2007-10-15) Difficulty: 2 of 5
The number N is obtained by rearranging the digits of a positive decimal whole number M.

Can M+N be equal to 99.....9, where the digit 9 is repeated precisely 2007 times?

"decimal" merely means it is in base-10, rather than base-12 (duodecimal), base-16 (hexadecimal), base-8 (octal) or base-2 (binary), etc.
