I'm not good at math

(This is a serious question)

Why can't zero be divided by?

It can, but not by those who live on a limit on the mind, codenamed: The Mirror.

Division is the inverse of multiplication.

So, if you multiply x by y, dividing it by y should give you back x. However, if you multiply anything by 0, you get 0. There is no possible method to get x back from that.

0*0=0

Somebody should define it.  I mean its been a while.  You'd think someone would at least make up a definition.

How could you fail that quote?

No, zero is not positive, it's just neither positive nor negative, that's what I meant in my post.

Look at the other quotes in the thread. I think some posts disappeared.
No, zero is not positive, it's just neither positive nor negative, that's what I meant in my post.
This is correct, but it would obviously mean that the result of division by zero can't have a sign either. In the solution presented in >>14 however, zero is positive.

Yeah, my great post disappeared.  It was a really good post.

of course you can divide by zero. a/0 = infinity

>>19
?????
0/0 = inf??? YOU FAIL!

>>20
Where is your answer then? I have always heard in any math class that:
-x/0 = -infinity
+x/0 = +infinity
0/0 = infinity

>>21
There is no answer. Division by zero is undefined. Limits are usually the easiest way to approach such problems.

PS: I'd ask my money back for those classes if I were you; not even my high school math teachers were that retarded.

0/0 = Not a Number

>>23
Alrightly, look, if it weren't a number, WHAT THE FUCK DOES IT REPRESENT, WHAT DOES IT CONSIST OF? LETTERS? TURTLES? DELICIOUS FUCKING CAKE?
NO, ITS FUCKING A NUMBER

>>24
It represents zero divided by zero. It consists of three symbols; two digits each representing zero and a mathematical operator representing division. It does not have a value, and is therefore not regarded as equalling any number.

>>11
Return a value? I think you should realize that math and computation are not the same thing. There is no concept of operations "taking place" over some length of time and "returning a value."

9:30 pm: Restate your assumptions.

>>26
So it raises an exception?

if 0*a=0
a is not any infinity, is ONE  of ALLthe numbers, we don't know each. So if we reached 0/0 in our calculus we have to step a little back and try a diferent aproach. Math is made of aproaches/tools

When you divide x by y, you're basically figuring out how many y's fit into x.  No matter how many 0's you have, you'll never end up with anything more than 0.  And even if x itself is 0, division still doesn't work, because who's to say 0 can only contain 0 0's?  Can't 0 also contain 2 0's?  For that reason, division is undefined rather than infinite--because it contains an infinite *amount* of answers, not a single infinite answer.

Yes, we could say that in R, 0/0 is R

How many zeroes fit a zero? As many as you want, therefore infinite.

'anything' != 'infinite'

YOU PEOPLE ARE FIGHTING OVER A DIVISION OF A NUMBER
THIS IS THE FUNNIEST SHIT EVER

>>37

You're on the wrong site if you want meaningful conversation.

>>36
"infinite" = "something"

let infinite = 0
and finite = 1
if infinite != finite then
1 != 0

BUT, if 1-1 = 0
that means if you do calculation like this
finite - finite = 0

that means finite = infinite if infinite+finite

final formula finite = infinite+finite

ps:i just waste approx 2 minutes writing this crap...discuss

Man you are Eistein!

>>40
You FAIL@math.
Infinite!=0. Infinite larger than you can imagine.

>>42
I have a good imagination

>>22
I was a little hurried there. Should have said undefined. I meant it results in an infinite number of answers, as in basically all real numbers. I was trying to shorten that down to just "infinity". Not that I see any truly superior answers here anyway.
In short: because the result is undefined, it is not specific, it is the range of all real numbers, from -infinity to +infinity.
