There was this person in Pre-Algebra (I'm in Middle School, okay? But I'm a Geometry kidder in the 8th Grade), and he was a Seventh Grader. I looked at his paper and I saw he knew how to divide by zero!!! :O

Apparently, it was like this:

3/1 - 2/1 = 1/0 = 1

I didn't know that! Now we know how Zero goes!!! :O :O :O

I'm flabbergasted! Bamboozled!

And I remember a Youtube video stating that too.

wtf?

um...3/1 - 2/1 = 1/1 = 1

Hmmm...shall I divide Zero by Zero?

100/0

0 + 0 = 0. Not 100. So go again.
0 + 0 = 0. Not 100. So go again.

It'll keep on like that for infinity. So logically, anything/0 = Infinity.

No, that was sarcasm. I guess that the :V smiley should've been used. Oh well. It was a funny moment since the person did not know to subtract fractions, yet it's also a sad moment too. I don't how sad, but oh well. He's going to have future troubles in Arithmetics now.

something divided by zero can be anything...think about it. Do some long devision with a zero...it's been awhile since I had that lesson, so I might be thinking of 0 / 0, but you CANNOT divide by 0...that guy in math class is screwing with your head.

No, he had trouble in math already, he's in a lower class than me, and I was just showing it off glamourizing it when in actuality it's just a silly mistake. He also added the denominator instead of making them common.

Well, if you use limits, you can actually divide zero by zero.

limn->0 n/n = 1

*moves topic*

EDIT: I think the coolest thing is this limit:

limn->oo 1n = e

Even though everybody would say that 1 power infinity would be one again, it's e. That's because the original assumption is actually

limn->oo (1+1/n)n = e

This formula can be mathematically proved.

Not infinite times. It fails to divide (or add) the first time. imo, it doesn't go infinite times. And yeah, I was going to state limits too, but Bliz, what you said is interesting. 1 power infinity tends to e, I just can't picture that (not that anyone can really picture infinity :/)

The mystery of 0s and infinity, such a sweet experience to the mind. I discussed about this with my friend for about 2 hours without a break and we were still not finished. But we didn't fight with math formulae, we just discussed infinity and 0.

It's like this:

limn->1 (1+1/n)n = 2
limn->2 (1+1/n)n = 2.25
limn->3 (1+1/n)n = 2.37
limn->4 (1+1/n)n = 2.44
limn->5 (1+1/n)n = 2.49

Now, if n is infinite and 1/n zero, then (1+1/n)n and 1n are equivalent as 1/n is zero. But as you can see how n in the limit increases, the number draws closer and closer to e. It is equal to e if n is infinite.

That's true, it requires some geometry. It's very similar with 2D graphics. It's rather basic coordinate calculation, but if you want some extra stuff like circles, elipses and more advanced stuff instead of just squares and rectangles, you do need some knowledge with trigonometric functions and calculations. You will eventually realize that you know the basic trigonometric transformation table (sin, cos, tan, ctg) from memory because you often work with it.

A computer scientist named James Anderson actually proposed that 0/0 could be defined as a number within itself, called nullity. Nullity is one of three 'transreal' numbers as Anderson describes it. The three numbers are Nullity, Infinity, and Negative Infinity.

Nullity is a numerical representation of a non-number that lies outside the affinely extended real number line.

If I may borrow from Wikipedia,

QuoteAnderson intends the axioms of transreal arithmetic to complement the axioms of standard arithmetic; they are supposed to produce the same result as standard arithmetic for all calculations where standard arithmetic defines a result. In addition, they are intended to define a consistent numeric result for the calculations which are undefined in standard arithmetic, such as division by zero.

Hehe. Zero divided by zero equals nullity.

So, instead of only one entity (infinity), there are three entities... This is a very interesting thesis. What about 00?

I was always amazed how 0/0 was impossible but Limn->0n/n = 1 was working just fine. Limits are amazing. They let us gasp into infinity and actually "freeze" it in our terms. Infinity times 2 divided by infinity is infinity again, but Limn->oo2*n/n = 2.
0 and infinity which don't quite seem to be the exact opposite seem to be connected either way. 0 is "in our world", it's there, you can imagine it, you understand it. But infinity is a completely different story. Through 0 and mathematics, though, infinity has been proven to be actually part of "our world" after all. It's a just a little bit harder to understand.

But aren't limits just approximations, though? *only knows very basics of cal, and some trig*
log11 = IMPOSSIBLE

I have a quack-job theory that all numbers are coefficients of units. For example, if I have 2 red apples, the would be 2 times apple. If I get another, that would be 2 times apple + apple = 3 times apple.

Thus, 0 would describe the same thing no matter what, and that would be null, the matter that doesn't exist.

so dividing by zero produces dark matter!!!!

No, limits are correct.
The logarithmic function is defined on a specific range. It simply doesn't work outside of it.

I agree with Blizz, limits are fun.. they mess with reality xP
Especially when we start to get conditions for our equations, like "If the equation exists" xP

Well, if you think about it logically, 1/0.1=10.. 1/.001= 1000. As you see the closer the number gets to 0, it becomes larger and larger. So logically n/0=infinite
Trying to think about it practically, if there exists 1 pie, and 0 persons are going to share that pie, how much does each person get? Uhh.. huh?

Chuck Norris divided by 0 once.. there was nothing left.

@kagutsuchi: We've already discussed this. It's called "Limits." You do them like this:
limn->< a number >(<an expression>)

And your aim is to find out what the expression is if n is <a number>. If the expression doesn't work out, you do what you did and start at a different number and work your way to the desired number, and see what the expression approaches.

So, as Blizz stated, limn->0( 1 / n ) = infinity.

EDIT:
I hate everything about Mississippi. We finally get to limits, and we do absolutely nothing with them. We just use the basic rules (the limit of (a + b) is the same as the limit of a + the limit of b. WOW, amazing)
