Question 1162716: Define factorial notation. (Assume that n is a natural number.)
1) n! = n + (n − 1) + (n − 2) + (n − 3) + ... + (3) + (2) + (1)
2) n! = n · (n − 1) · (n − 2) · (n − 3) · ... · (3) · (2) · (1) · (0)

3) n! = (n − 1) · (n − 2) · (n − 3) · ... · (3) · (2) · (1)
4) n! = (n − 1) + (n − 2) + (n − 3) + ... + (3) + (2) + (1)
5) n! = n · (n − 1) · (n − 2) · (n − 3) · ... · (3) · (2) · (1)
Explain how to evaluate 10!.
Substituting n = _____ into the correct formula above results in 10! =_____

.

The only correct formula is (5).

The rest are incorrect.

Calculate 10! on your own and DO NOT disturb the tutors with such miserable questions without necessity.

Also, it is a BAD STYLE to come to the forum with such questions.
