Hatred of Eleven III

Number Theory Level pending

We define an "Eleven Hater" as a number that is not a multiple of eleven, but becomes a multiple of 11 11 when any one digit is removed.

For clarity, consider a 3 digit number a b c \overline {abc} . if a b c \overline {abc} is an "Eleven Hater", then a b , a c , \overline {ab}, \overline{ac}, and b c \overline{bc} should all be multiples of 11 11 . Note that the order of the digits are not to be altered.

Find the sum of all "Eleven Haters" from 1 to 1,000,000.


The answer is 504990.
