Hello,

I have a question, say I have 40 switches, each being able to be in 9 different positions. How many different unique combination could I make? A formula would be cool too so I could learn to fish.

Thanks!

This isn't combination or permutation, isn't it just the number of choices? He has 40 switches and they can each be in 9 different positions, 40x9?
