What is (-4)! ?

The expression "(−4)!" refers to the factorial of -4. However, the factorial function is only defined for non-negative integers (i.e., 0, 1, 2, 3, ...).
The factorial of a number "n," denoted as "n!", is defined as the product of all positive integers from 1 to n. Specifically:
n! = n × (n - 1) × (n - 2) × ... × 2 × 1, for n ≥ 0.
For negative integers like -4, the factorial is not defined because we can't take the product of integers in the same way for negative numbers.
Therefore, the factorial of -4, or (−4)!, does not exist.
