Question
What is -5!

Answer
Gene,

n! is nothing but 'n factorial'. Factorial is the product of all positive integers less than or equal to n.

Hence,

5! = 5 * 4 * 3 * 2 * 1
5! = 20 * 6 * 1
5! = 120

I believe this solves your problem. Let me know if you need additional information.

All the best. :)
