My CS professor just told my class of 200 people that 1 is a prime number.

You can practically hear centuries of mathematicians rolling over in their graves

    It's not a prime number because it can't be divided by itself "and" 1 (because they're the same number and shit)

    @filthyranter if (x && x) print("Hey this works"); unfortunately I don't think you can apply your logic here.

    @BradSharp In this context 'and' is set union (counter intuitively), not logical conjunction, so that doesn't have anything to do with it. A prime must have exactly two divisors.

    If 1 is a prime, then the fundamental theorem of arithmetic is no longer true.

    I mean it's called the *fundamental* theorem of fucking arithmetic.

    A working set of definitions:

    Prime: a natural number with exactly 2 divisors

    Composite: a natural number with > 2 divisors
