There are 3*2*1 = 6 of them.

The answer will depend on how many digits you have at your disposal. Working with the 10 digits, and barring leading zeros, there are 8,877,690 numbers.
-99
how many different ways can you use the digits 3 and to write expressions in exponential form/ what are the expressions
You would need infinitely many digits to write all numbers. However, to write all whole number (integers) you would need 4243.
There are 3*2*1 = 6 of them.
89,999 different numbers i guess

Different schemes have different id numbers of different lengths.
There are 7,290 different 4-digit numbers that can be formed from the digits 1-9 without repetition.
There are 41 of them.
