Can someone please explain factorials versus permutations to me in a way that MAKES SENSE? fucking teacher, fucking textbook, fucking notes dont help me at all. whenever i see the ! sign my mind goes blank. WHY IS THERE AN EXCLIMATION POINT IN MY MATH PROBLEM.
factorials are easy but then i see the ! and i dont know what to do. i cant keep anything in my fucking head! i hate teachers who give me tests with 15 days til graduation. thats lame lame lame.

"If you're alive, I probably hate you."
