About Factorial :

• The multiplication of all positive numbers or less than equal to a particular positive integer, indicated by that number plus an exclamation point, is known as factorial in mathematical.
• As a result, factorial seven is expressed as 7!, which means

        1 2 3 4 5 6 7.

About Negative Factorial :

• Something simplest one comprehend was just as described in the following:

• $4! = 4 X 3 X 2 X 1 = 24$

        $3! = 3 X 2 X 1 = 6$

        $2! = 2 X 1$

        $1! = 1$

        $0! = 1$

       $-1! = \frac{0!}{0} = \frac{1}{0}$

• That very same rationale holds true for many other negative numbers.

• As a result, the factorial of negative values is Does not exist.
