get the numbers and order them from biggest to smallest.
If you have to use all four digits - 1349. If you can use them in a sum 9-4-3-1 = 1
Including the leading zero, the smallest number you can make from the digits 03418 is 01348. Without the leading zero in the ten thousands column, the smallest number you can form from the digits 03418 is 10348.
It is 7/98.
Using those 4 digits 6451 is the largest odd number you can make.
If the digits given are to be separately: 8 - 5 - 3 - 0 = 0 will give the smallest possible absolute value.
In order to make the smallest possible number with a set of digits, you want the least valued number in the greatest valued place. For 5 digits, you would want the least digit, 0, in the ten thousands place. You would then want the second least digit, 3, in the thousands place, and so on. For the digits 0,3,5,7,9 the smallest possible number would therefore be 03,579 or 3,579.
00000 or 11111
Assuming you cannot use zero, 24578.
13,579 or .13579 . If I'm allowed to repeat digits, then you are 11,111 or .11111 .
