If you want just combinations:
There are 5 1 letter words
2 letters --> 5*4 = 20
3 letters --> 5*4*3 = 60
4 letters --> 5*4*3*2 = 120
5 letters --> 120
= 120 + 120 + 60 + 20 + 5
= 325

I would object to some of the other tutor's "words", such as ae and de.
I missed acre, cedar and cadre, tho.  I might have thought of them eventually.
