For this type of "the largest number which..." questions, you need to advance from left to right, using the largest possible digit in each case. For the first two digits, that would be 9, for the third digit (the right-most digit), the largest digit which will make this possible is an 8.
The smallest number is 5,789. The largest is 98,750. The difference is 92,961.
That depends a lot on how often you may repeat each digit, and what operations are allowed. If you just want to write a four-digit number, using each digit once, start by writing the largest digit on the left, then continue with the second-largest, etc.
Four different digits that sum to 6 are: 0, 1, 2 & 3. The largest odd number that can be made from these is: 3201.
