We call a number special if every digit in the number either is a 1 or borders a 1. For example, 11111, 13, 141, 1441, 515151, and 101 are all special, but 10001, 222, 122, and 1333 are not special. How many 2-digit numbers are special?
The numbers 10-19 qualify
And the reverse of these numbers from 12 - 19 also qualify ...i.e., 21, 31, 41, ......, 91
So .......that's 10 + 8 = 18 numbers
