becaus eas others have said there is a philosophical argument to this which is the argument i follow and believe, in my view 0.9r does nto = 1 does that make me a bad person or stupid ? I dont think so it makes me disagree with you end of.

if you cant convince me how do you think you are going to convince anyone else ?

try explaining it to me, walk me through it dont just dismiss me because i dont have a Degree in mathematics.

Sorry to butt in, but whilst I fully understand what you're saying about the little bit that's not being accounted for by the "maths heads" (:D), it is not 0.1r.

0.1r is 0.1111111 etc. If it were to be added to 0.9r, the result would be 1.1r. The little bit some people on our side of the argument are referring to is actually a cartload of zeros after the decimal point, with a one on the end, ie:

0.000..........01 :)

0.0r1 or something ?


unfortunatel I was typing so fast i didnt realise what i had typed

:o
 
0.99r = 1 has been proven using basic mathematical algebra, namely:

x = 0.99r
10x = 9.99r
10x - x = 9
x = 1

this is proof uses the most fundemental rules of algebra (multiplying, dividing and subtracting). If you chose to believe that 0.99r does not equal 1, then you are also stating that the most basic rules in mathematics are in fact wrong! Quite a bold statement to make, is it not?

Maybe you should do a bit of background reading. Why should someone on here have to teach you things just to show you that you're incorrect.

You won't accept 1=0.9r, but when given a proof, you return with 'well that's not good - I don't understand it'.

You don't need a degree in maths, I sure as hell don't have one. It would help if you understood it before dismissing it really wouldn't it :)

ok then an A Level ? Im pretty sure i didnt do that in GCSE maths :p

No it isnt, read the other god damn thread.

0.9r = 1 is a maths concept and can be rpooved using maths.

Outside of maths you can choose to take it as 0.9r or 1. This has been discussed to death in the original thread!

Because most of them (like me) have themselves proven this, or something like it and are happy that the methods used are sound.

If you feel that they aren't, then you have the right to try to disprove it. Unfortunately the only arguments I've heard thus far are along the lines of "It doesn't make sense to me for this to be the case. So how can it be the case? It can't!" which are not proofs, but opinions. I'm all for those people to spend some time investigating further how and why the mathematics is correct (or incorrect) and presenting their findings on the matter.

As an aside, using philosophy to dispute something like this is dubious at best. You can dispute *anything* using philosophy.
 
If you find Jokester's example a bit confusing, what don't you udnerstand about the very simple example i've given 3 or 4 times already:

x = 0.99r
10x = 9.99r
9x = 9
x = 1

But in the same sense, you can also take it to be equal to 7 if you want. I refer you to :

Philosophically speaking, I mean.

That proof is not a "trick", it's very basic maths.

so are you in fact saying that multiplication, subtraction, addition and division are in fact, all wrong?

Based on the conveniences created by previous maths heads, I agree that your methods are sound.

Its those conveniences we're questioning.

Of course you can, and thats what we're doing.

I expect there is a shorthand way of expressing it akin to X.Yr, but regrettably I'm not one of the maths heads and so don't know what it is. :D

There is no short hand for it - it would be pointless. It would be signigying the number at the end of an infinite sequence. An obvious contradicion in terms.
