should 1 divided by zero=infinity? because nothingness can fit into somethingness an infinit number of times correct?

1 divided by 0 is undefined.

The answer depends on the sort of math your doing. In your everyday experience it's simply undefined, if you ever go into higher mathematics there are a ways of defining what the answer is but these involve things like taking a number and psuedodividing it by its psuedoinverse.

You can define it, but only if it's attached to a function of some sort... just a straight out 1/0 is always undefined.

No, you typically get some mundane number like 3/4 or 0 if you define it using calculus. It depends on what function it's part of.

im assuming a(1) reality has infinit space,

so basically "1" can contain infinity

No, the answers vary. In linear algebra the answer happens to be zero.

That's probably the closest you'll get to anything supporting your point. However, to be clear about this, that is NOT the same thing as 1/0=infinity.

Then why are you asking this question, half the stuff you do in derivative based calculus is figuring out how to compute divide by zero problems.

The useless cases some people make are ridiculous. Essentially it's our verbiage enabling philosophical discussion.

If

x/0 = ∞

then

x/∞ = 0

and then 0*∞=x

But x is any number.

So what the ****?

x/0 = ∞

then

x/∞ = 0

and then 0*∞=x

But x is any number.

So what the ****?

That's because both 1/0 and 0*∞ are undefined values, as explained. So no, nothing in that equation works.

I'm merely explaining why you can't divide by 0.

its undifined because we are not smart enough to conceive it, but theres very well an answer. we might discover it in the future perhaps

Why do we need to find 1/0?

Do we ever use it?

Do we ever use it?

You can't bilaterally define 1/0, provided that 0 is a real number. If you want to define 1/0 you need to do so unilaterally. If you approach 0 with positive numbers, it would give plus infinity, otherwise, it is minus infinity.

On the other hand, if 0 is a matrix, there could be a non-zero matrix whose multiplication with another non-zero matrix would equal 0.

No, it's undefined because it has been mathematically proven to be so. That's the difference between math and, say, physics. It's possible to have absolute proof in math.

On the subject.

0^2/0^1=0^1 I'm sure no one can disagree with this.

but 0^2 and 0^1 both equal 0, since x^1=x and 0^2=0.

So, 0/0=0

and if that's the case, then 0^1/0^1=0^0=0

Even though x^0=1 for any other number. (Zero isn't really a number anyway)

So then, 0^0/0^1=0^-1

0/0=0

0^-1=1/0

1/0 therefore must equal 0.

And that, can go for any number, since 2/0 would equal 0 as well, because double 0 is 0.

This contradicts all 1/x graphs that show an increase the closer x goes to 0.

But my point is, this is another reason why it's undefined.

0^-1=undefined.

Also, you should simplify before the operation so you wouldn't even end up with 0^-1. Remember PEMDAS.

I honestly thought my closing statement of the post would prevent another person telling me it's undefined.

PEMDAS?

We did BODMAS in like key stage 3, but what is PEMDAS?

power, exponential, multi, divide, add, subtract?

what about brackets?

And why does it apply?

You can replace it with whatever you want. I figured I'd correct you right there, as any continuation beyond that point would not be logical.

Parans Expons Multi Divid Add Sub

It applies because you need to simply your expons before you divide. Basic algebra stuff.

Wrong in oh so many ways. Just because you got the correct answer, does not mean your proof was logically valid in any way. 0^2/0^1=/=0^1

a/x, where a is a number that is not 0, is thought to equal in infinty in calc. Just like a/infinity, where a is not infinity, is thought to be 0. This seems to be supported by the graph of a/x.

or as King Kandy showed us by limits.

0/0 is even stranger, as 0/0 could, theoretically be any number.

No, not quite correct. Because, approaching the left, x=negative infinity. So the limit does not exist because left and right bound limits don't agree.

Very true. It's been a while since I've used limits.

I to think that undifined is correct, as x approaches 0 in a/x the solution begins to go toward either infinity or -infinity.

1/x integrated is in theory, 1/0 (x^-1 becomes (x^0)/0)

but in reality it's ln(x).

Where in the world did you get that notion? the antiderivative of X^-1 would just be X^0, or zero. Not X^0/0. However because all constants derive to zero, x^0 does as well, so ln(x) is the integral.

The way I was taught calculus was the rule for integrating:

add one to the power, then divide by the power.

differentiation is the inverse.

That somewhat works (however not in this situation, the dividing part is to cancel coefficients which doesn't apply here), but that doesn't work for 1/x, because even though you could conceivably see the integral as 0, the derivative of 0 is most certainly not 1/x.
