How many different ways can the first ten letters of the alphabet be arranged?

There are 3,628,800 ways to arrange those letters. See explanation for details.

We can solve this task in 2 ways:

First letter can be chosen from all 10, next from 9, third from 8 and so on until you have only one letter left. 
So the number of ways to arrange the letters can be calculated as:

n=10×9×8×7×6×5×4×3×2×1=3,628,800
