Answer:

Let n be a whole number, where n! is defined as the product of all whole numbers less than n and including n itself.

The general formula of factorial can be written in fully expanded form as n! =(n-1)!

we know with absolute certainty that 1! =1, where n=1

n! =n×(n-1)!

1! =1×(1-1)!

1! =1×(0)!

1! =1×0!

1! =0!

so yes 0! =1 is correct
