The ten digits (integers) 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are frequently reffered to as the Arabic numerals.
However, they were invented (we do not know by who) in India around 500 AD.
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.
There are 720 permutations of 3 different digits from the ten digits 0 to 9, including leading zeros.

1000
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.
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]
Of the ten digits, 0 is the only one that is divisible by 9.
