For a simple equation like that, it may seem that way.

Anything more complicated than that and writing it longhand would be horrendously time-consuming and complicated!

Additionally, good practice would be to define the variables you are using before writing the equation.

ie.

Let:
mass = m
acceleration = a
force = f

F = ma

That way, anyone coming along should be able to know exactly what you are talking about.

I can see that, honestly i can but then if you worte it longhand wouldnt a helluva a lot mroe peoplle be able to understand it ?

is algebra just a mathmatical language designed to confuse all none mathmaticians :p


actually I am seriouly consiidering taking up a maths course now, wheres me local college at.........

Feel free to correct me :o (Assuming people all voted with their opinions)

Whether or not I voted, and how I voted if I did vote, which I may or may not have done, is not known to you. You know that I have been arguing the 'not equal' case, but how one has posted is independent of how one voted, if indeed one did vote, which may or may not have happened.

So how did/would you have voted originally? Now? Next time this thread comes up?

NB - Nice wordplay ;)
 
I voted yes, but i dont know much about prooving...

I have maths at 2pm today, and so i'll ask my maths Teacher...She what he thinks;) (he wont have a clue)

Just a quick reword of what DF said for people who do not want to read all of his post:
Just because I posted it does not mean I have voted and I could have voted in opposite relation to my post, and you would not know.

EDIT: I am not trying to start an argument I am just pointing out how pointlessly long and easily confusing to the skim reader your wording is.

After due deliberation of the merits of adopting a flexible and revealing posture, taking into account the subtle nuances of the situation at this particular moment in time with emphasis on the scientific minutiae and abstract ponderings that are on the table, and having carefully examined the positions of those interlocutors already entangled in this agitated affair, whilst one certainly feels a certain propinquity for myriad participants, one feels that at this juncture it would be as sage a proposition as requesting an aperture in the cranial cavity.

I am suitably chastened by the fact that I've posted so damn many replies. Mea culpa.

However, I am shocked. Really, utterly surprised at people's opinions. If someone wants to say that "philosophically" 0.9r!=1, they may do so, and I respect the opinions of Harley & Co. for restricting their arguments to the field of philosophy (where, unlike in Maths, there are valid opposing opinions and there can be debate), and memphisto for accepting the truth - but the people I rebutted were those claiming that, in essence, they were smarter than Stephen Hawking and every single other mathematician in history (without, of course, offering proof - perish the thought!), and people saying that, despite incontrovertible proof - even "God" himself telling them - they would refuse point blank to accept that 0.9r is mathematically equal to 1. AcidHell2 and Xenoxide, I mean you.

I left at 2 AM, halfway through the thread (it's reached 11 pages on my screen, I left just before page 8), in order to get my 4 hours of sleep before school today.

I just came back, and read all of the remaining 4 pages of 80 posts each (it's taken >70% of my laptop's battery), and all I see is the same old arguments being repeated over and over, only with the naysayers getting less and less logical, and Alpha & Co. getting more and more frustrated. Understandably so.

If you want to post in a thread:
a) Read the first couple of pages to get an idea of the debate and the facts (I did post Alpha's proofs on the first page, which would probably have addressed 90% of the posters here)
b) Please ensure that, if you're going to argue something, you have at the very least a modicum of knowledge, and accept your limitations. I'm just under 17, studying for my Maths A levels, and I seem to have a better grasp of basic math concepts than certain posters here who would presume to challenge the entire mathematical world. And I know when I can't answer, I know when I'm beaten, I don't stick my head into places I can't get it out of without bits of it terribly mangled in the process and looking like a fool.

And Haly... tsk tsk ;) Mean, but well played Alpha.

You, sir, are evidently not sufficiently well acquainted with the considerably complex requirements that must be met as a prerequisite to initiating the process that may, depending on the validity of one's arguments and the firmness and unshakeability of one's beliefs, eventually lead to the winning of a debate and the utter defeat of your opponents in it.

:D

Maths advanced far enough for us to reach the real answer by 1750. You're 250 years behind the time. If you studied maths (even at A Level) you'd know maths is way more advanced than worrying about sums of infinite series (especially convergent ones!)

I did study maths, I did maths and further maths at A level and got two A's...

I've also studied some of the interesting parts of my fathers open university maths course - one of which dealt with infinite series and infinity in general. A lot of the infinity stuff was very poorly specified and extremely difficult to actually do anything concrete with.

Another thing to think of if that since an infinite series will take forever to evaluate, the 0.99999999999r (x) will be one step further ahead of 9.9999999999r (10x). So, if you ever try to evaluate the series at any time you will end up with 9x =
9.9999999999
0.99999999999
=
8.99999999991

Which is not 9 as the proof requires...

I'm sure most of you won't agree with that, but then I don't agree with lots that you have said.

I just don't think that it is possible to have a complete and unequestionable proof for this problem.
