If you're allowed to use zero as the first digit, then that would be 10!/7! = 10 * 9 * 8 = 720. If you're not allowed to use zero as your first digit, then it would be 9 * 9 * 8 = 648.
No. Natural numbers are positive (or zero) whole numbers - without digits after the decimal point.

Yes. Any set of digits without a fraction or decimal point is a whole number. The whole numbers are all the numbers you say when you count (or their negatives).

In the numbers 1-9 each number has 1 digit and there are 9 of them, so that's 9.In 10-99 each number has 2 digits, and there are 90 of them: 2x90 = 180There are 900 three digit numbers [100 through 999]: 2700 digits.There are 9000 four digit numbers: 36000 digits.90,000 numbers with five digits: 450,000 digits.900,000 numbers with six digits: 5,400,000 digits.Then 1 number with seven digits: 7 digits.Add them up and you have 5,888,896 digits.
It is possible to create a 3-digit number, without repeated digits so the probability is 1.
No, because a quotient requires two numbers. Given the two numbers it is quite easy to work out the number of digits in the quotient.

Digits is how many numbers you have in a number. If you have the number 4 it has one digit if you have the number 20 it has two digits and if you have the number 558 it has three digits. So basically in the number 1085 it has 4 digits because there is 4 numbers in it, the numbers are 1,0,8 and 5. Hoped you understand.

Armstrong numbers are the sum of their own digits to the power of the number of digits.

I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24
3.14 has a finite number of digits. All numbers with a finite number of digits are rational. Pi has an infinite number of digits, AND the digits don't repeat in a regular pattern. (Numbers with repeating decimals are rational as well.)
