Assuming that you are able to use all four digits as many times as you wish, then there are a total of 256 different numbers available. 4 choices for the first digit, 4 for the second, 4 for the third and 4 for the fourth. 4 x 4 x 4 x 4 = 256If each may only be used once, then the total will be just 24. 4 choices for the first digit, then 3 for the second digit and two for the third digit. The fourth digit will always be the single choice of the remaining digit, so the calculation will be 4 x 3 x 2 x 1 = 24.
