Why 0! is equal to 1 | Proof | AsapMath
Factorial of a number is product of all integers from 1 to that number. According to the definition of factorials , it is defined for integers greater than 1. We have come across many occasions where we need to use factorial 0 (0!) Actually 0! is equal to one. We have used that without any proof. Have you ever thought about it how to prove it or deduce it?
