You can make 4*3*2/2 = 12 numbers.
First digit can be any of 3, second can be any of 3, as can third and fourth so your answer is 3 to the fourth ie 81
Oh, dude, I mean, like, there are 4 digits in 1230, right? So you can totally make 4-digit numbers by using each of those digits once. That's like, 4 factorial, which is 24. So, you can totally write 24 different four-digit numbers using 1230 without repeating any digit. Easy peasy!
106------------------------------------------------------------------------------------------------From Rafaelrz.You can make, 4P3 = 4!/(4-3)! = 24, different 3 digit numbers using 1, 2, 3 and 4.
If you want 4-digit numbers, there are 24 of them.
