Re: 0

0/0 is undefined. Any number divided by zero is undefined, meaning a value for that operation does not exist in the real numbers, or complex, numbers.

Some of you are repeating basic theorems of division such as x/x = 1 or 0/x = 0. However, you are leaving out an important part of those statements. Those are true iff x =/= 0. Division by zero simply is an operation that is not allowed in our mathematics.

 

Re: 0

You'll know you've successfully divided by zero when, as you do your math homework, the Universe spontaneously explodes.

 

Re: 0

LOL. Neon's a math-related major, so I trust his word.

 

Re: 0

I'm gonna go try divide my no cookies. I probably won't let you know if I succeeded, but I'm sure you'll know anyway

 

Re: 0

someone said anything divided by itself equals 1. and there's confusion does 0/0=1 or does 0/0 = 0

these points ill make have alread been made to some degree, but id like to explain in my own words.

If you think of each part of the equation literally, as what each part means.

0 / 0 = 0

Nothing, is going to be divided or 'split into equal sections', the number of divisions there will be is 0.

If you take nothing, no matter what number you try to divide it by you will always get nothing, because there is nothing to divide.

now...

0/-1=0

0/39=0

0/0= ERROR on the calculator.

It id undefined, because there are no values. 0 is a number, but it has no value.

So divide a number with no value, by another number with no value, there are no values at all to speak of, therefore there is no equation, which is why it is undefined.

also...

this any number divided by itself equals 1 business...

1 goes into 1, one time.

2 goes into 2 one time.

0 going into 0? again, there are no values. numbers, but no values, therefore no equation, so there can be no answer.

.... i actually dont know if im right, i dropped outa school. but yeah. thats my take on it.

 

Re: 0

im no math genius, but as far as im considered if you've got nothing and you want to give it away in equal shares to nothing, then your just standing there wondering what to do. I'd go with undefined

 

Re: 0

wow, one number made a four paged thread, imagine if you talked about all of the numbers up to infinity! LOL

anyways, heres how i see it...

if 1/1=1
then why 0/0=1 ?

yet any # divided by zero is zero....

yet any number divided by itself is one....
so in conclusion..........

we cant conclude it..... thus.......

its undefined...... simple logic? i think not

 

Re: 0

this is a sum that officially is declared impossible just like 5/0

 

Re: 0

"Result of function is undefined."

MS Calculator FTW.

i explained that in my previous post, the very last post on page 3.

it essentially says that the number 0 is a number, but has no value. if an equation is only made up of 0's, then the equation has no value in it, and therefore no equation, which is why it is undefined.

0 divided by a number with value, 0/9=0. 0/-5=0 0/13879=0.

these equations have values within the equation.

0 / 0 =

There are no values in that equation, numbers, but no values. Therefore no equation.

 

Re: 0

the solution to 0/0 could be any number but there isn't a definite solution hence the term "undefined"
the solution to x/0 couldn't be any real or complex number so it does not exist, but we could theoretically defined it as a new kind of imaginary number. (say j where we define j = 1/0; we could not do this to the solution of 0/0 because it would require the new imaginary number to equal all other real and complex numbers, which is impossible so 0/0 is it's truly undefined)

 

Re: 0

I cant believe i didnt see this debate earlier. 0/0 can answered depending on the equation you use to create it. *silnetly points at the limit definiton of the derivative* but if you are just using raw numbers 0/0 is simply undefined where as any other number divided by zero is infinity depending on the way you look at it.


Also out of curiousity since you and me keep butting heads on this Reaker what math have you taken? (i am just curious because i could believe it being more than me but sometimes it doesnt matter because the meat of the course)

 

Re: 0

i took triple maths as a part of my a-levels, which is a 2 year period immediately before university in england. then i decided that maths was boring and choose computer science as my undergraduate degree (major)

 

Re: 0

took triple math and than said "eh, math is boring". LOL! Took you 2 years to figue that out?

I'm currently a freshman in college and plan to major in mechanical engineering.

 

Re: 0

I am sorry but the sounded like complete jiberish to me because right now i very little understanding of how colledges work much less colledges outside the U.S. So if you could give me a clearer answer or atleast a more mathy answer it would be much appreciated.

@ Eonmaster if you insinuating math is boring i absolutely beg to differ otherwise goodluck in colledge.

 

Re: 0

@ LordKerwyn, math can get boring sometimes. Since I scored low on the trigonometry entrance test, I'm taking college algebra, which I had years ago, so I'm bored.

One test and I go from Calculus 1 to Advanced Algebra? Thinking about it makes me wonder on the entrance testing, considering I beat 80% of everyone else in the Algebra test.

But algebra and trig are in the same class 1 semester algebra and 1 semester trig. Mess up one test and screwed.

 

Re: 0

Ouch i think i was lucky in the fact i was able to use AP scores to show my profiency instead of taking an entrance exam.

 

Re: 0

My high school didn't have many AP programs. Could have done the calculus one, but the class was faster than regular cacl. and I didn't feel like doing the extra homework. So I took reg. calc. my senior year. Oh well, easy A for me!

Thats good since Chemistry is killing me with only a low C. I suck at Chem. always have, always will.

 

Re: 0

whoa..... i'm only a freshmen studying communications engineering
