How many whole numbers from 99 to 131 contain the digit 1 exactly once?
Answered by Ms. Sue
I'm sure you can count from 99 to 131.

Answered by brain MATH
I wouldn't want to do that. It wouldn't work out. Are there fast ways to do the problem? Or do I just have to count?

By the time you posted this you could be through the counting.
