Think about the fraction \frac{1}{x}. As x gets smaller using positive numbers, the fraction  gets bigger to the point where the value increase to \infty. As x gets bigger with negative numbers (i.e  -1 < -0.1), the value of the fraction goes to -\infty. We leave it undefined because mathematicians aren't sure where its limit is -\infty or \infty.
