Well think about it. If you divide by something less than 1, your number gets bigger.


2 / 0.1 = 20

Same thing when it's negative, except now the answer is negative. So, if x gets really close to 0, it will be very big, or a big negative number. Remember, "getting close to 0" could mean from the negative side just as well from the positive.
