You fucking retards....

Anything divided by zero is the original number.
10 / 0 = 10. You simply didn't divide, because it's zero.

Anything multiplied by zero is zero because you're saying there's zero original numbers.

>> No.15579126

>>15579008
That's not the question. You answered 1/(1/0)=0. While that is true, In reality you just proved that 1/0 is infinity, since 1/infinity=0.
What you're meant to answer is simply 1/0 by itself. And you kinda already did accidentally, but you don't get it. Try to figure that one out friend.

>> No.15579130

>inb4 nooo 10 / 1 is the original number idiot
Both are true.
10 / 1 is saying you split 10 up into a bunch of ones and then add them back together again.
10 / 0.0000... is infinity.
10 / 0 is saying that you don't divide at all in the first place.

Here's a useful rule of arithmetic that we'd like to be true.

0*a=0 for any number a. 0 times anything is 0.

Another useful rule is that for any number a there exists another number a' such that a*a'=1. For example 5*(1/5)=1. Say there was a number 0' such that 0*0'=1. This violates our previous rule that 0 times anything is 0.

Either we agree to not let 0' exist (in other words 1/0 is invalid) or we get rid of one of the rules.

0 is not a number, it is the absence of a number, like infinity. That's why infinity/0 = 1

>> No.15579205

>>15579198
Infinity is the opposite of an absence of numbers.
Infinity is the inverse of 0.
Multiplication is NOT the inverse of division.

That is correct, but since you are retarded and lack a faustian spirit, you didn't go all the way to the real answer.
1/ (1/x) = x
so 1= x * (1/x)
1 / (1/0) = 0
1= 0 * (1/0)
anything times 0 equals 0

1=0

>>15578959
multiplication is "start from 0 and add a number x times" so it makes sense to choose not to add any
division is "start from a number and split it into x chunks" so it makes sense for "zero chunks" to be an impossible concept

>>15579274
For something to be negative or positive, it must have a defined magnitude. infinity doesn't have a defined magnitude. Saying negative infinity is just like saying negative zero. Both don't exist.
"Negative infinity" is just a convenient way of saying getting to infinity through the negative path. That is to say, no matter which path you take, negative or positive, at the end, the destination is the same, just infinity.
Think about it in terms of reality. There is a direction. You can move forward or backwards in space (Positive or negative). You can say I moved "+2 feet", meaning you moved forward by a mgnitude of 2 feet. But once you are outside of reality (Which is what infinity is, it is not "Real", it is beyond real. Just like Zero is beneath real, or lack of reality), there is no space, no directions. No positives, no negatives. Since there is no space, there is no "where" to move to, there is no "2 feet" neither in the positive nor in the negative, there is no magnitude of anything at all. It's all just infinity. Just infinite magnitude, infinite everything, beyond human comprehension. There is no "negative" of this infinity.

In short, I could say something like this
-(infinity) = (-1)(infinity) = (infinity)

>tl:dr Negative Infinity is not a thing

When dividing imagine splitting an object like an apple into equal groups.
So 1/1 is 'splitting' the object into an equal group of 1, a whole apple, 1/2 splitting into equal groups of two leaving two halves of an apple at the end 0.5, etc.
So what would it mean to divide an object until it is zero equal groups? It's a kinda paradoxical statement.
Like would it mean you just keep dividing into infinitely smaller groups? What would be the number at the end then?
Does it mean the apple just wouldn't be?
There isn't really an answer for it.
