    Can a human do what a computer cannot? For example dividing by zero.

    Computers can divide by zero. They can return either infinity or just "not a number".

    Both humans and computers can divide by zero. They both get the same answer - it has no meaning.

    If you try to get a computer to divide by zero, you usually get this message on the screen:

    "Congratulations, you are the 1100111th customer to attempt division by zero!

    This computer will now self destruct as a token of our sincerity."

    I agree sideshowbob. A computer equates infinity: it hangs. This is why computers are programmed with an error message displaying the computer cannot compute such a calculation.

    However I would argue:

    (((x+1)/(0+1))-1)=x

    exactly the same as:

    +0
    *0
    -0

    Zero does not exist. There is nothing there to calculate with...

    Zero is the same as any other number. It is not a "thing".

    In a BBC english TV program called QI (recommend viewing)

    the panel was asked

    ' Is zero a odd or even number? '

    The answer is given as ' even '

    Because it lies between two ones

    -1 and 1

    Go figure

    That's the answer I would have given. It's also even because it leaves no remainder when divided by 2.
