The factorials of negative real numbers are complex numbers. At negative integers the imaginary part of complex factorials is zero, and the factorials for -1, -2, -3, -4 are -1, 2, -6, 24 respectively.
Why is it not possible to have a negative factorial?
Explanation: One of the main practical uses of the factorial is to give you the number of ways to permute objects. You cant permute −2 objects because you cant have less than 0 objects!

A zero factorial is a mathematical expression for the number of ways to arrange a data set with no values in it, which equals one. The definition of the factorial states that 0! = 1.
What is the rule for negative integers?
RULE 1: The quotient of a positive integer and a negative integer is negative. RULE 2: The quotient of two positive integers is positive. RULE 3: The quotient of two negative integers is positive. If the signs are different the answer is negative.
What is a factorial of 1?
In mathematics, 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, The value of 0! is 1, according to the convention for an empty product.
How do you find the factorial?
To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720. For 7!

Do 2 negatives make a positive?
When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.
Are ints negative?
An int is signed by default, meaning it can represent both positive and negative values. An unsigned is an integer that can never be negative. If you take an unsigned 0 and subtract 1 from it, the result wraps around, leaving a very large number (2^32-1 with the typical 32-bit integer size).
