Question

How many different ways can the first 10 letters of the alphabet be arranged?

Step-by-step explanation:

First letter can be chosen form all 10, next from 9, third from 8 and so on, until you have only one number 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=362800
