If the 10's dice is 3 and the 1's dice is 1, you get 31.

What do you need to roll to get a 0 and 100?

I could see this working if the dice were 0..9 and you add one to the
final result,
but you said that dice should be 1..x.  So do you subtract one from each
digit, then add one to the final result?

Example:

10's     1's
1           1     => (1-1)(1-1)   => (00)+1  => 1
4           1     => (4-1)(1-1)   => (30)+1  => 31
10        10    => (10-1)(10-1) => (99)+1  => 100
