Let the original number be ABC, where the numerical value is .
The reverse number would be CBA or numerically .
.
.

A, B, and C can take on values from to .
For each value of B, there are A,C values.

So there would be or number pairs that meet this criteria.
If leading zeros aren't allowed (like 012/210), then reduce the B values allowed by 1, and then or 72 number pairs are allowed.
