How many number combinations are possible with 0123?

Answer 1

16 if you include 0 starting

12 if not

That is not correct.

0123 is a 4-digit number = (n)

therefore n! = 4! = 1*2*3*4 = 24 (if 0 is included as I assume that is the question)

123 is a 3-digit number = (n)

Therefore n! = 3!= 1*2*3 = 6

Answer 2

With four digits (0, 1, 2, 3) and no repetition allowed, the number of possible combinations can be calculated using the permutation formula. Since the order matters, the number of permutations is 4! (4 factorial) which equals 4 x 3 x 2 x 1 = 24. Therefore, there are 24 possible number combinations with the digits 0, 1, 2, and 3.

Answer 3

Oh, what a happy little question! With those four numbers, there are 24 possible combinations. Just think of all the beautiful possibilities you can create with those numbers, like painting a serene landscape with each combination. Remember, there are no mistakes, just happy little accidents in math and art.
