You need to take more math. I have a bachelors degree in it. So, I can tell you 0/0 is one of the seven indeterminate forms we teach in calculus.
The problems in calculus are such that we require the student to transform the problem involving 0/0 in it in some way that we can determine it. Yes, calculus has us determine the indeterminate.
Suppose we want to find out what (x^2 - 2x + 1) / (x - 1) when x is 1.
If you plug x = 1 into the above, you'll get 0/0. This will happen hundreds of times to the calculus student. It happens so often, that they actually get used to it.
The numerator in this case factors into (x - 1)*(x - 1). One of these will cancel with the denominator leaving x - 1. Now, we plug in x = 1 into this simplified expression and find that it is 0. So, our 0/0 wound up being 0 in this example.
So, there, I WAS able to tell you what 0/0 is. But, that doesn't mean God exists or doesn't exist.
My articles prove he doesn't exist.
