It can be calculated as factorial 44! = 4x3x2x1= 60

Oh, dude, you're hitting me with some math vibes here. So, if you have 6 digits to choose from to make a 4-digit combination, you can calculate that by using the formula for permutations: 6P4, which equals 360. So, like, you can make 360 different 4-digit combinations from those 6 digits. Math is wild, man.
There are ten combinations: one each where one of the ten digits, 0-9, is excluded.
There are twelve possible solutions using the rule you stated.
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.
If the digits can repeat, then there are 256 possible combinations. If they can't repeat, then there are 24 possibilities.
It can be calculated as factorial 44! = 4x3x2x1= 60
With repeating digits, there are 33 = 27 possible combinations.Without repeating any digits, there are 6 combinations:357375537573735753
The order of the digits in a combination does not matter. So 123 is the same as 132 or 312 etc. There are 10 combinations using just one of the digits (3 times). There are 90 combinations using 2 digits (1 once and 1 twice). There are 120 combinations using three different digit. 220 in all.
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.

There are 5,040 combinations.
9,000 - all the numbers between 1,000 and 9,999 inclusive. * * * * * NO. Those are PERMUTATIONS, not COMBINATIONS. Also, the question specified 4 digit combinations using 4 digits. The above answer uses 10 digits. If you start with 4 digits, you can make only 1 combination.
There are 210 4 digit combinations and 5040 different 4 digit codes.
