0/-infinity, which is just another indeterminate.

Actually, 0/-infinity equals 0. It's not indeterminate. An indeterminate division would be something like infinity/infinity.

    Actually, the limit of 0/x as x goes to -∞ is 0. Infinity is not a number, it's a concept.

    An indeterminate division would be something like infinity/infinity.

    The limit for x to ∞ of x/x is 1.

    — Arien

      lim[x → ∞](x/x) = 1
      lim[x → ∞](2x/x) = 2

      Now which one do we take?

      Makeshifts last the longest.

        lim x → ∞ x/x was just an example to show that dividing two numbers that approach infinity is determinate. I didn't mean to suggest that the "division" of infinity by infinity has the value 1 (or 2, or any value for that matter).
