A dumb math theory

[ultimategamer]

Your statement is both wrong and right, Afro. Heres your logic:

1/3 = .3333333
2/3 = .6666666
3/3 = .9999999

BUT

.999999 = 1, so 3/3 = 1

Whys is .999999 = 1 though? Lemme show you.

if x = .999999
then 10x = 9.99999
if we subtract these two statements we get:
10x - x = 9.99999 - .99999
so:
9x = 9
x = 1
1 = .9999999

Any number divided by itself is = 1, except if those numbers are zero and infinity. It is actually possible to come up with a real number by dividing them using limits, but thats calc stuff and is pretty complicated.

And yes, when you divide any non-zero non-inifinite number by zero you get infinity. Thats math. That makes sense. Also, EvilBean, your right 10 x 0 = 0. BUT, think of it this way. multiplication is the opposite of division, so doesn't it only make sense that you get 2 different answers? Dividing 3 and 5 will get you a far different answer than if were to multiply 3 and 5.

No. That's the limit, but any real number divided by zero is NOT infinity.

i've seen that before...somewhere.

and what i meant about 0 = value or 0 = nothing is like this,

in math 0 = value
in reality 0 = nothing

so if you want some info u think u can use relating to the world, universe etc, you gotta use 0 = nothing, otherwise it's just a theory. like me throwing a baseball at your head it has to go half way, then half way again and again and again and each time it will take X amount of time to travel that extra half way...so the ball would never hit your head. but in reality, it certainly does.

[IAMTHEEVILBEAN]

I was thinking about this topic and came up with this.

0*7 = 0
I hope you all know that anything multiplied by zero is zero.

Ok....If 0 represents nothing, should't 7*0 = 7. Since you are multiplying 7 by nothing. If 0 was infinity, anything multiplied by it would be infinity.

Think about it.
You can't have 7 infinity, or 68 infinity (0*7 and 0*68 ), so it just goes to 0, which is infinity.

Just a thought.

[Moogy]

0 * 5 = 0

OMG I FIGURD IT OUT

[alainbryden]

Iamtheevilbean, the X operator is non-ordered, unlike the / operator. So you can't say that 7x0 and 0x7 can result in two different answers. It doesn't work anyways because 3X2 means I have 3 twos, 5X6 means I have 5 groups or six. 0x7 means I have no groups of 7, so 0. 7x0 means I have seven groups of 0, 0+0+0+0+0+0+0 = 0

[alainbryden]

It's interesting that you should say that 0 is infinity however, because in theories where, the universe is circular, if you consider that negative numbers are more of an intangeable concept than positive numbers, you could say that the numbering system, like the universe, is an infinitely large sphere, just two dimentional. If you could travel in a straight line infinitely instantaneously, you would end up in the same spot in the universe, but the logic of the theory. Of course it is an impossible concept, even to conceive how something like that could be conceived. Anyways, following this pattern, the numbering system starts at the indescribable 0 and continues infinitely to the number infinity, which represents zero after traversing the whole number system. It is the other conceptual impossible end that meets the zero to tie the cirle. Of course this is all a BS theory and the universe could never begin to be comprehended, but it's neat.

0 is nothing, so it doesn't count as anything. The sole reason you CAN'T DIVIDE BY 0 is because it is nonexistant.

[The_Q]

in addition, why do we have a word for nothing if the word itself means a void? Same reason to have 0, to acknowledge the void.

Black holes are where God divided by zero...

[Auranceus]

what about if you divided a number by an infinitely small positive decimal (as in really really close to zero)?

wouldn't it be infinitely close to infinity?
couldnt the infinitely small positve decimal also be just about zero? and then with that thing with the threes and the algebra wouldn't it be zero?

then again it would also depend upon the whole numerator... so maybe 1/<insert infinitely small positive decimal> = infinity
while 2/<insert infinitely small posotive decimal> = 2 infinity... which becomes infinity, leaving 1/<insert infinitely small positive decimal> to not equal infinity but an incredibly huge number... (if i understand the concept of infinity, that is)

therefore infinity/<insert infinitely small positive number>= infinity, and if the infinitely small positive number = 0 then inifnity/0 = infinity... waahhhh i confused myself!

i think it makes sense... but... meh... oh well

[DracIV]

Anything divided by 0 is undefined. It just can't happen. And an infintesimal number is close enough to 0 that you get an undefined # (infinite). You can only have infinite, no 2x infin or 5x infin. It is all still infin.

[The_Q]

There is no way to reach infinity but it does exist. Like faster than light travel. It's possible, but not anytime ever.

[GuidoHunter]

"Infinity" is just a term to verbally represent something that is REALLY BIG, so it doesn't actually exist in any definite form.

Why do we have a word to describe somthing that we cannot describe?
I stopped asking why words mean what they do, as its way to f'd up.
So 7/0=inf....it has to be undefined!
If 0=nothing, reality and theory, how can you put nothing(reality) or an undefined number(theory) into somthing and expect an outcome?
I dislike the whole zero concept in math.
Everything i said up there is probably majorly flawed but oh well.
