    This has two interpretations:
    1. Factorial of 0 is 1
    2. 0 is not equal to 1

    Both are mathematical facts.
    What's the problem?

    @cst1992 It has a third interpretation, where "!0" is equal to 1. Technically it does not say this, but I believe that is what is meant.

    But, would javascript agree?

    @cst1992
    != is not used standard math but instead ≠ is used. On the other hand, in programming there is no postponed unary operator !, so 0! is meaningless for programmers but means factorial for maths. Given that there are no spaces to differentiate whether ! is referred to 0 or to =, mathematicians should interpret it as 0! = 1 (factorial of 0 equals 1), while programmers should interpret it as 0 != 1 (0 not equal to 1)
