Arranging letters. In how many ways can I arrange the six letters A, B, C, D, E, F?
The number of ways to arrange the six letters is given by the factorial of 6, denoted as 6! and calculated as follows:
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720
Therefore, there are 720 ways to arrange the six letters A, B, C, D, E, F.
