Permutations Example 2

How many ways can you rearrange the letters in the words MAN with the letter M always in front.

There's only 1 way to put the letter M.

For the remaining 2 letters A and N there is 2 x 1 = 2 ways

1. AN

2. NA

So, with M always in front, the number of combinations is 1 x 2 x 1 = 2 ways.

Let's check

1. MAN

2. MNA

Again, this is correct
