This problem is equivalent to 4 cases problem :
U U U U
case #1 => 10 possibilities
case #2 => 10 possibilities
case #3 => 10 possibilities
case#4 => 10 possibilities
So, we have Total combinaisons = 10 x 10 x10 x 10 =10,000

There are ten digits from 0-9, so there are 10 possibilities.
There are 4 times this can happen, so there are:
10 x 10 x 10 x 10 possibilities, which is 10,000 possible combinations.

Go to your excel spreadsheet.
In the first box (a1) put a zero.
Next cell to the right (b1), put in
=a1+1000
Copy the content of b1 into cells c1 to j1.
This gives you ten columns, each titled with a different thousand (0 to 9000).
go to a2. enter
=a1+1
copy the content of cell a2 and paste it in all cells from a2 to j1000.
This gives you 10,000 cells, each one with a different number from 0 to 9999.
Select all. Format, Cell, Numbers: try to get it to write all four digits, even when the preceding figures are 0's.
Good luck.

There are a billion combinations! no one is going to give you all of them. You should figure it out yourself!
