Digits or decimal digits more specifically. The decimal system has 10 unique digits 0-9.
9
There is nothing "in" digits. Digits are single characters representing the ten integers from 0 to 9 (inclusive).
Perhapsf you specified the number of digits. e.g. 0-9 with two digits.
The answer is 10P3 = 10!/(10-3)! = 10*9*8 = 720

How many permutations of 3 different digits are there, chosen from the ten digits 0 to 9 inclusive?
Perhapsf you specified the number of digits. e.g. 0-9 with two digits.
The answer is 10P3 = 10!/(10-3)! = 10*9*8 = 720
There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.There are none.Any number made by using the digits 0 to 9 once is divisible by 9 and so not a prime.
1000
Digits
That is 8001. For a number is divisible by 9, the digits must sum up to 9 (or a multiple of 9). So for 8000, the digits sum to 8 [8 + 0 + 0 + 0 = 8]. So you're only 1 away from 9 [8 + 0 + 0 + 1 = 9]
you can image the 3 digits as a counter 0 0 1 0 0 2 ... ... ... 9 9 8 9 9 9 every digit uses 100 times a 6..... 100*3 digits = 300 sixes :)
