Math is harmful to human health? Or did I make an error?

Factorials really aren't confusing. To put it in mathematic terms, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n.
For example, 4! = 4 X 3 X 2 X 1 = 24
They probably have many uses, but I remember using them in permutations. That and making recursive code in C++.
Looks like I did make an error. It should have been:
? x (?-1) x (?-2) x (?-3)...[(?+1)-?] = ?!, assuming x is greater than or equal to 5.
It was just a bit of a joke I went waaaay too far out there to make and analyzing it this much makes it even less funny, LOL. Ah well. Live and learn.

I wish more math were taught. The math education in my area growing up was pitiful. We didn't even have calc courses in high school. We'll never produce engineers if we don't get past basic algebra in high schools. |

so... would ! and ? be variables? or are they random symbols standing for numbers, like pi? o.o
if they're variables, i get it... if not, im lost x.x |

Well, in Hrae's case, '?' is a variable, but ! is a symbol for factorial. And factorial is what Hrae showed in there: 4! = 4 x 3 x 2 x 1 = 24
3! = 3 x 2 x 1 = 6. You get the drift, right?
