I DIVIDED BY ZERO!

[GAX]

OH SHI-

[Starrodkirby86]

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.

[GAX]

wtf?

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




Hmmm...shall I divide Zero by Zero?

[fugibo]

Think about it.

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.

[Starrodkirby86]

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.

[GAX]

Well, dividing by Zero isn't infinity, it's undefined...

[legacyblade]

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.

[Starrodkirby86]

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.

[Blizzard]

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

lim_n->0 n/n = 1

*moves topic*

EDIT: I think the coolest thing is this limit:

lim_n->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

lim_n->oo (1+1/n)ⁿ = e

This formula can be mathematically proved.

[fugibo]

But 0 goes into anything infinite times, dangit!!!

[Fantasist]

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.

[Blizzard]

It's like this:

lim_n->1 (1+1/n)ⁿ = 2
lim_n->2 (1+1/n)ⁿ = 2.25
lim_n->3 (1+1/n)ⁿ = 2.37
lim_n->4 (1+1/n)ⁿ = 2.44
lim_n->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.

[Fantasist]

Hm... interesting, thanks for explaining it Bliz ^_^

[Blizzard]

We learned that proof in 1st or 2nd semester, can't remember. I think it's pretty interesting. I remember my prof telling us somebody's quote. It was something like "There is nothing that was so fascinating for the human mind as infinity."

[Phasedscar]

I was about to say "I know there's a way to divide by zero.

Unfortunately I took algebra in a USA high school.  Need I say more?

[Blizzard]

That means that you know there is a way, but you don't know it? xD

[Phasedscar]

lol pretty much.

I'm not bad at math, I just don't care for it so I never really studied it hard.

[Blizzard]

In college you have to study it whether you like it or not. >.< I'm not at a math college, but computing science still requires a lot of math.

[Phasedscar]

I just haven't taken the math class for that yet.

You need a lot of math geometric art like 3D animation (which is my major) and I'm minoring in Art, but it doesn't require anything higher then basic algebra and geometry.

[Blizzard]

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.

[Fantasist]

In college you have to study it whether you like it or not. >.< I'm not at a math college, but computing science still requires a lot of math.

My professor said to us: "Math is the heart of computing science". and yeah,

"There is nothing that was so fascinating for the human mind as infinity."

(Okay, I know I'm probably necro-posting, but please please please hear me out. I have something decent to add to this discussion.)

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,

Anderson 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.

[Blizzard]

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

(Necroposting is allowed if you have something relevant to say. ^_^)

Contrary to popular belief, gravedigging, or posting in an old topic, is for the most part ok. This means as long as your post is relevant and important enough to post in a topic that has been considered dead, it is ok. Unless of course, the topic you're posting in is several months old, then you would be better off just starting your own topic. This also means posting just to say "Cool" or "I agree" or anything else pointless in nature will result in the deletion of the post and/or locking of the topic.

[Fantasist]

transreal numbers? Sounds interesting.
(goes to Wiki)

[Blizzard]

*necropost* This picture is very appropriate for the situation discussed here.

[fugibo]

I believe that all numbers are pointers.

And 0 is the pointer to NULL, the God of Wcism.

Therefore,  x / 0 is God.
0 / 0 is reality.

[Blizzard]

I was always amazed how 0/0 was impossible but Lim_n->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 Lim_n->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.

[fugibo]

But aren't limits just approximations, though? *only knows very basics of cal, and some trig*
And and what about logarithms?
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!!!!

[Blizzard]

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

[Kagutsuchi]

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.

(I know the topic is old, but it was on the first page..)

[Blizzard]

Another interesting thing is definitly 0 * oo. Which is stronger? 0 or infinity?

EDIT:

Spoiler: ShowHide

[fugibo]

I still think x over 0 = infinity.

[Reno-s--Joker]

THIS is the secret to making infinite amounts pie!!!!!!!1!






..... which no-one will end up getting.

[fugibo]

@kagutsuchi: We've already discussed this. It's called "Limits." You do them like this:
lim_{n->< 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, lim_n->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)

[Blizzard]

Too bad. :/ Limits are also used in order theory to determine the convergation of orders. One ironic thing is that I missed out the day in school when we learned limits. xD I had no problems catching up, though.

[RoseSkye]

Can someone give me an example of -infinity- in our world that keeps coming up.

[Blizzard]

Take a number order. 1, 2, 3, 4... It goes on and on. It never ends.

[fugibo]

Infinity's not a number. It's the limit of a series with no bounds.

[RoseSkye]

Take a number order. 1, 2, 3, 4... It goes on and on. It never ends.

Its the number that never ends it goes on and on my friend.
You started counting and you didn't know what it was.. but you continued counting just because ..

Technically no human can count to infinity .. I don't remember what I read but it said something about in a humans life time they can only count to x..

[Blizzard]

All I'm saying is that infinity is an abstract term. You can't define infinity in reality.

[RoseSkye]

All I'm saying is that infinity is an abstract term. You can't define infinity in reality.

There must be a number before infinity.

like 9999999999999999999999999999999999999999999 and 9.. infinity.

[fugibo]

Please, stop. Wikipedia is your friend.

[Blizzard]

oo - 1 = oo

One less than infinity is also infinity.

[RoseSkye]

Please, stop. Wikipedia is your friend.

Of course, you couldn't pick up sarcasm.
So I would say that.. it is everyones friend

Of course, having a symbol that symbolizes eternity.. and a numeral system that of tries to keep tabs on a finite amount of things in our world/universe must not be irony... and my post must not have been sarcasm pointing out the irony of it all.
