No, a permutation is not when your perm goes bad. Hee hee. Permutations are ways to find combinations of things that don't have repeats. So, for example, if you are picking a 4 didget code for your garage door, but can't have repeated numbers you have 10 choices for the first number, then 9 choices for the second number, 8 choices for the third, and 7 for the last number. Multiply them together and there are 5040 combinations of 4 numbers with no repeats. For the students, this is where I make boxes and then fill them in.
