4p3*3p1 equal to 72 ways
Including leading zeroes, the answer is 720. If you don't include leading zeroes, then 600.
Without repeating digits (not digets!) and without leading 0s, 600 of them.

Without repeating, 4. With repeating, 8.
4 x 3 x 2 ie 24
The number is 9875.
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!
1,956 different numbers can be made from 6 digits. You can calculate this by using the permutation function in a summation function, like this: Σ6k=1 6Pk = 6P1+6P2+...+6P5+6P6 What this does is calculate how many 1 digit numbers you can make from 6 digits, then how many 2 digit numbers can be made from 6 digits and adds the amounts together, then calculates how many 3 digit numbers can be made and adds that on as well etc.
