The number is: 36725918 In descending order that is: 98765321 The pairs of numbers that have as many digits between them in both are: 3,9 5,8 6,7 So there are three pairs.

To find the smallest possible whole number using the digits 3, 6, 1, and 8, we need to arrange them in ascending order. The smallest whole number would be 1368. This is because in whole numbers, the digit in the leftmost place value should be the smallest possible digit available.
10 + 23 = 33 Lowest possible real number 97 + 86 = 183 Highest possible real number 02 + 13 = 15 Lowest possible number 97 + 86 = 183 Highest possible number
The greatest possible number is 888... (repeating).

Since a number can have infinitely many digits, there are infinitely many possible combinations.
Yes, it is possible for an account number to consist of only 7 digits.
The different digits have different values.
It is possible to create infinitely many numbers, of infinitely many different lengths, using the digits of the given number. Using each of the digits, and only once, there are 5! = 120 different permutations.
There is only one possible combination of a 13 digit number created from 13 digits. In a combination, the order of the digits does not matter so that 123 is the same as 132 or 312 etc. If there are 13 different digits (characters) there is 1 combination of 13 digits 13 combinations of 1 or of 12 digits 78 combinations of 2 or of 11 digits and so on There are 213 - 1 = 8191 in all. If the characters are not all different it is necessary to have more information.
If the digits are only used once, each, the largest possible number would be 97,531

The number system we commonly used, known as the decimal system, has 10 digits (0 to 9). It is possible to use other number systems, with a different number of digits. Any numbering system based on the same principle (the principle of place-value) must use 2 or more digits.
The sum is 22 times the sum of the three digits.
