I have started this thread in an attempt to answer everyone's questions that will never affect anyone's lives unless they major in that particular subject. Please be polite and wait or me to finish a question before posting another. Thank you.

[spoiler=0/0 is undefined]

 

12/3 = X. X = 4. We know this because the quotient times the denominator equals the numerator. 3x4 = 12.

 

Now, if 0/0 = X, we would get the answer by multiplying X times 0 to get zero. Now how do we know what to put in for X? Do we say X = 0? That works, but someone else can say X = 2. They are also right because 2x0 = 0.

 

Unfortunately, as a single variable, X can only hold one value, so we cannot define X. Therefore, 0/0 is undefined.

 

Now what if you put a different number in the numerator? Let's say 2. Now we have 2/0 = X. To find X, we would say 0X = 2. We would then say WTF? In this equation, we would never get a value for X.

 

This is why any number divided by zero is undefined.
