I always, and still do, believe that (1/0) is "undefined" (because 0 is in the denom.) It couldn't be possible that 1/0 is infinity, right? Because the smaller the number toward 0, the higher the answer? I assume that wouldn't work in many cases.

1/0 is undefined
0/1 is 0

anything with 0 on the bottom is undefined in a fraction

however, you could say that lim (x->0+) 1/x = +infinity :p

It approaches infinity. Most calculators simply say "undefined," however. It's not equal to infinity, but it's not just "undefined."

The limit as it x approaches 0 of 1/x is infinity, but 1/0 itself is not.

Take the fraction, use the slope method, put it on a line. Slope = undefined.

I know that you believe you understand what you think I said, but I'm not sure you realize that what you heard is not what I meant.
