    "There are sort of two reasons. For one thing, when you divide one number by
    another, you expect the result to be another number. So in particular, look
    at the sequence of numbers 1/(1/2), 1/(1/3), 1/(1/4), ... . Notice that the
    bottoms of the fractions are 1/2, 1/3, 1/4, ..., and that they&#39;re going to
    zero. So if there&#39;s a limit to this sequence, we would take that number and
    call it 1/0. So let&#39;s see if there is.

    Well, the sequence turns out to be 2, 3, 4, ..., and that goes to infinity.
    Since infinity isn&#39;t a real number, we don&#39;t assign any value to 1/0. We
    just say it&#39;s undefined.

    But let&#39;s say we did. Let&#39;s say that infinity is a real number, and 1/0 is
    infinity. Then look at the sequence 1/(-1/2), 1/(-1/3), 1/(-1/4), ..., and
    notice again that the denominators -1/2, -1/3, -1/4, ..., are going to zero.
    So again, we would want the limit of this sequence to be 1/0. But looking at
    the sequence, it simplifies to -2, -3, -4, ..., and it goes to negative
    infinity. So which would we assign to 1/0? Negative infinity or positive
    infinity? Instead of just assigning one willy nilly, we say that infinity
    isn&#39;t a number, and that 1/0 is undefined."*

    Wow, you just revolutionized maths

    You can&#39;t divide by zero as the result is undefined. Is it infinity? Who can say
