Digit 1 = 10 choices (0,1,2,3,4,5,6,7,8,9)
Digit 2 = 10 choices (0,1,2,3,4,5,6,7,8,9)
Digit 3 = 10 choices (0,1,2,3,4,5,6,7,8,9)
Digit 4 = 10 choices (0,1,2,3,4,5,6,7,8,9)
Number of combinations = 10 x 10 x 10 x 10 = 104 =10000

one digit: 5 ways two digits: 5 * 9 ways three digits: 5 * 9 * 8 ways four digits: 5 * 9 * 8 * 7 ways ... ten digits: 5 * 9! ways So if you have to use ten digits, then the answer is 5 * 9! = 1814400. If you can use anywhere from one to ten digits, then the answer is: 5 * (9! + 8! + 7! + 6! + 5! + 4! + 3! + 2! + 1) = 2045565
Perhapsf you specified the number of digits. e.g. 0-9 with two digits.
It is a decimal representation where, after a finite number of digits, all subsequent digits are 0 [or of them all 9].
To write the number 1 using all ten digits (0-9), you can use the following expression: 1 + 0! + 2 - 3 + 4 + 5 - 6 * 7 + 8 - 9 = 1. This equation utilizes addition, subtraction, multiplication, and factorial operations to combine all the digits from 0 to 9 to ultimately equal 1.
It's finite (although very big). If a decimal between 0 and 1 is exactly 100 digits long, then there are 10 ways to choose the first digit, 10 ways to choose the second, and so on. This gives us 10100 ways to choose all 100 digits, which is very large (it's a googol, in fact) but not infinite.

120 if numbers can start with 0, otherwise, 96.
It is a decimal representation where, after a finite number of digits, all subsequent digits are 0 [or of them all 9].
There are 10 numbers in all including 0. The first space can be filled in 9 ways (as we have to exclude 0). The second through sixth spaces can be filled in 10 ways as 0 can be included. Totally, 9 x 10 x 10 x 10 x 10 x 10 or 9 x 10^5 digits can be formed if repetition is allowed.
To write the number 1 using all ten digits (0-9), you can use the following expression: 1 + 0! + 2 - 3 + 4 + 5 - 6 * 7 + 8 - 9 = 1. This equation utilizes addition, subtraction, multiplication, and factorial operations to combine all the digits from 0 to 9 to ultimately equal 1.
The largest numeral that can be formed using all 10 digits is 9876543210. This number contains all the digits from 0 to 9 in descending order, making it the largest possible arrangement. Any other arrangement would result in a smaller number.
It contains all the digits from 0 to 9
Distinct means different from all others. So there can be no repeated digits. Thus, 4124 is not possible because there are two '4' digits. There are 9 ways to choose the first digit (1-9, as 0 is not possible). Subsequently, there are 9 choices for the second digit, since there are 10 possible digits (0-9), but we can't pick the same one as the first digit. Next, there are 8 ways to choose the 3rd digit, since we can't choose the same as either of the first two digits. Finally, there are 7 ways to choose the 4th digit. The answer is 9 * 9 * 8 * 7 = 4536.
There are only two digits used in binary: 0 (zero) and 1 (one).
