I like tacos. Proof, look it up in the taco reference manual.

Q2)

My answer is not significant, as it is not large. My proof complies with the fact that there are multiple ways to yield distinct answers to 0/0, such as lim x -> 0 = 0 in 0/x=0 and lim x -> 0 = inf. in x/0 = inf. Or something

I pick A because when you think about the logic, how many times can you take nothing away from nothing. Since there is nothing to take away, it results in nothing. Paradox?

@mattchewy

You can take away anything. lol.

9001 * 0 = 0 will be correct.
43925823094i * 0 = 0 will be correct.

yea.

"I pick A because when you think about the logic, how many times can you take nothing away from nothing. Since there is nothing to take away, it results in nothing. Paradox?"

In answer to your question, no, that is not a paradox. That is 0 - 0. Which is quite definitely 0. Really, if you are presented with 0/0 with no context, I would say that, since a*0 = 0, 0/0 is indefinite. However, there is almost always a context, and that gives it meaning. There is rarely a need to evaluate it.

For example, say you are doing a common task such as finding the intersection between two lines, a and b. If you have both in standard form:
ax + b = cx + d
you can easily rearrange to:
ax + b - d = cx
b - d = (c - a)x
(b - d)/(c - a) = x
Here, the context gives the fraction 0/0 meaning, because, in reality, you should almost certainly interpret the answer differently. Here, the answer of 0/0 = x means that the two lines are identical (Note: This means they intersect at all x, in answer to the original question), and if you're writing a program, you could not extract any meaningful data from the answer of 0/0, so you would have to take action based on the fact that they are identical.

DIRECTLY FROM MY UBUNTU LINUX CALCULATOR:

"Division by zero is undefined"

So I say D, because the calculator is always correct. [/nationalism]

I believe the correct answer is D.
It is undefined because division is simply multiplication of the numerator by the reciprocal of the denominator, so, since 0/1 is undefined:
0/0
0 * 1 * (undefined—0 has no reciprocal)
