This is a question involving permutations and possibilities.Nine numbers, four slots to fill, and I'll assume no duplicates for now.
9!/(4!(9-4)!)
= 6*7*8*9 / 24
= 7*8*9 / 4
= 7*2*9
= 63*2
= 126
There are 126 unique four-digit numbers that can be arranged with the digits 1-9.
If duplicates were allowed, there would be 94possibilities, or 6,561.
