The first digit can be any one of the ten symbols, 0 thru 9. For each of those . . .
The second digit can be any one of the 9 that weren't used in the first place. For each of those . . .
The third digit can be any one of the 8 that you haven't used yet. For each of those . . .
The fourth digit can be any one of the 7 that haven't been used yet.
Total number of possible arrangements = (10 x 9 x 8 x 7) = 5,040
