I believe there would be a total of 1,000 combinations possible, if you're counting 000-999. If you're only counting whole numbers 100 and up (numbers in the hundreds) I think there are 900.
Possible solutions - using your rules are:- 11,13,17,31,33,37,71,73 &77
99999
If repetition of digits isn't allowed, then no13-digit sequencescan be formed from only 5 digits.
985,958,895,859,589,598. It should be 6. Hope I helped. Possible you want 4 digit numbers using the digits 9 8 and 5 and you want to know how many of those there are?

It is possible to create infinitely many numbers, of infinitely many different lengths, using the digits of the given number. Using each of the digits, and only once, there are 5! = 120 different permutations.
If repetition of digits isn't allowed, then no13-digit sequencescan be formed from only 5 digits.
Possible 5 digit combinations using 5 digits only 1 time is 5! or 5*4*3*2*1 or 120. Using 5 digits where numbers can be used 5 times is 55 or 3125.

There are 4 possible numbers if the digits are not repeated; 18 if they are. Those are 3-digit numbers, assuming that zero would not be a leading digit. If zero is allowed for a leading digit, then you can have 6 for the non repeated, and 27 if repetition.
6 possible 3 digit combonations
There are 2 possible digits for the first digit (3 or 4), leaving 3 possible digits for the second digit (5 and 6 and whichever was not chosen for the first), leaving 2 possible digits for the third. Thus there are 2 × 3 × 2 = 12 possible 3 digit numbers.
There are 60480 numbers.
To create the numbers 1-100 using the digits 2, 0, 1, and 2, you can use various combinations and operations. For example, you can form numbers like 1 (by using 2-2+1), 2 (using one of the 2s), 10 (by combining 2 and 0), and higher numbers such as 20 or 21. By creatively using addition, subtraction, and combinations of the digits, you can generate many numbers up to 100. However, some numbers may not be possible with the given digits and operations.
