You could look at it as `limit of x/x as x approaches 0`, which would be 1. Or you could look at it as `limit of -x/x as x approaches 0`, which would be -1. O

You could look at it as `limit of x/x as x approaches 0`, which would be 1. Or you could look at it as `limit of -x/x as x approaches 0`, which would be -1. Or you could look at it as `limit of x/0 as x approaches 0`, which would be +/- infinity, depending on which side you approach 0 from. Or you could look at it as `limit of 0/x as x approaches 0`, which would be 0.

I think the third case is `limit of c/x as x approaches 0`. It can only approach 0, c/0 is still undefined.

  Not exactly, as c also has to approach 0. So you have two limits, and their order matters.
