I am taking a class this september, and I am trying to read up a bit before it starts. I have a question on the exclamation mark (the "factorial"?).
I think I understand the formula, (I hope ) but when I am actually working with this thing in a calculation, do I have to worry about which comes first? (like I learned last year that multiplication comes before addition) do I do, for example, subtraction before the exclamation mark?
