Question

[Keikan]

why can't you divide by zero?

i need you opinion on this. thanks.

[toco004]

anything divided by 0 is 0.

[brotherdoobie]

"There are sort of two reasons. For one thing, when you divide one number by
another, you expect the result to be another number. So in particular, look
at the sequence of numbers 1/(1/2), 1/(1/3), 1/(1/4), ... . Notice that the
bottoms of the fractions are 1/2, 1/3, 1/4, ..., and that they're going to
zero. So if there's a limit to this sequence, we would take that number and
call it 1/0. So let's see if there is.

Well, the sequence turns out to be 2, 3, 4, ..., and that goes to infinity.
Since infinity isn't a real number, we don't assign any value to 1/0. We
just say it's undefined.

But let's say we did. Let's say that infinity is a real number, and 1/0 is
infinity. Then look at the sequence 1/(-1/2), 1/(-1/3), 1/(-1/4), ..., and
notice again that the denominators -1/2, -1/3, -1/4, ..., are going to zero.
So again, we would want the limit of this sequence to be 1/0. But looking at
the sequence, it simplifies to -2, -3, -4, ..., and it goes to negative
infinity. So which would we assign to 1/0? Negative infinity or positive
infinity? Instead of just assigning one willy nilly, we say that infinity
isn't a number, and that 1/0 is undefined."*

o ya i need your own answer not googles

[Cheese]

Because it's not a number.

Wow, you just revolutionized maths :o

You can't divide by zero as the result is undefined. Is it infinity? Who can say

That&#39;s what Google said son.....Not good enough for you?...Meh&#33;

[destroyerofevil]

Becoz 0 is neither a prime nor a composite number. It also isnt a natural number.

Close this topic please...due to retardation and redundancy. ;)

Peace brotherdoobie :lol:

Retardation? :huh: Me just stating mathematical facts. :angry: If any1 around here is retarded its u. :angry:































Nah jk dood. :)

You can&#39;t divide things by Zero cos he isn&#39;t here yet :rolleyes:

Is it taking me somewhere for breakfast? :unsure:


edit - I take it you haven&#39;t looked out the window today? :lol: I won&#39;t be needing a coat :rolleyes:

[thewizeard]

Ok, great theory, but then lets say I have 1 apple, and I don&#39;t divide it so 1. apple/0 ....surely I have still got 1 apple and not zero apples? :)

What you said is that anything divided by 0 is 0, which is blatantly untrue. Anything multiplied by 0 is 0, yes. The same does not apply for division

[J'Pol]

Any number dived by 0 provides infinity as the answer.

If you divide by 1, you get the same number

If you divide by 1/2 you multiply by 2

If you divide by 1/4 you multiply by 4

If you divide by 1/123456789 you multiply by 123456789

So the smaller the number you divide by, the higher the number you effectively multiply by. It&#39;s a reciprocal thing.

As 0 (which is a number) is infinitely small, then that is the same as multiplying by an infinitely large number.

So "my" apple would suddenly expand to the size of the universe....

Practical application of theoretical concepts is a little tricky ;)

Choosing not to do something to an object does not automatically lead to the equation object/0.

We&#39;re talking maths here old bean, not arithmetic. Or fruitering for that matter.

[thewizeard]

I thought for a minute that we had stumbled on the solution for the food shortage supply in our world... by the way, what has " old beans" got to do with the subject matter? :)

Edit: typo of course...

I think current theories suggest that the Universe is finite....just very big.

So, to quote Pratchet, it would be the size of the multiverse :blink:

:unsure:

[thewizeard]

:o Well...I just hope nobody divides my apple, or those old beans by zero, while I am holding it/ them... :fugley:

I always though that it was infinite, within a finite expanding space. Maybe I picked that bit up wrong.
