0!=1 is both mathematically correct (because 0 factorial is 1), and logically correct (since 0<1).

I found this interesting.

    I think 0!=1 was first realized by programmers then mathematicians proved it.

    That's why whitespaces matter.

    The one that always got me was e^iπ + 1 = 0

    @segfault0xff I am not sure, but it's probably coming from complex analysis.
    I took a course on it (but don't remember much). Using the complex field to solve real integrals sometimes gives rise to things like this. There's alot of tricks being used and i and π sometimes just pop up for no (appearnt) reason.
    Check it out on Wikipedia if you're interested. Pretty cool stuff.

    @YousifMansour I just found it weird that an irrational number to the product of an imaginary number and another irrational yields an integer.
