The smallest two digit number is 00 (a number used as a wire gauge) and the largest is 99, so the difference between the largest and smallest 2-digits numbers is 99 (99 - 00)
The greatest 5 digit number is 98765. The greatest 5 digit number that doesn't contain any of those digits is 43210. The difference between them is 55555.The two five digit numbers using all ten digits once and only once between them that sum to the largest value are 97531 and 86420. They sum to 183,951 and have a difference of 11111. These two numbers are not unique ... you can switch any pair of digits between the two numbers as long as you keep them in the same position without changing the sum, though this will change the difference.
The sum of the number of digits in all the numbers between 31 and 400 inclusive is 1041.
The smallest number is 5,789. The largest is 98,750. The difference is 92,961.

If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.

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.
The sum of the number of digits in all the numbers between 31 and 400 inclusive is 1041.
The smallest number is 5,789. The largest is 98,750. The difference is 92,961.
