How is the value of 0! 1?
I see. What about the factorial of negative numbers? Is that even possible?
Hmm, that's an interesting question. The factorial function is generally only defined for non-negative integers, so the factorial of negative numbers is not well-defined. However, there are some extensions of the factorial function that allow for the computation of factorials of negative numbers, but they involve complex analysis and are beyond the scope of this conversation.
