New AnswerI was also wanted to help you but I am doing a music Player project. Sorry, but Yes it is just multiplication of number till you reach 1.
I'm assuming that's Maths right? So 7! means 7 factorial. Which means 7 times 6! This translates to 1*2*3*4*5*6*7. Which gives 5040. 8! would mean 8 times the factorial of 7, so 8*5040 or 1*2*3*4*5*6*7*8.
