ok thats a cop out for a start.

you know what i am getting at, any multiplication of 0.999 other than by 10 means that the final number will be different to 9.

in this instance it is 5

and if it is 5 then the equation doesnt work.

On the contrary. If there are an infinite number of numerals, there will be no last numeral to equal 5. So it isn't a cop out, it's the basis for why that's wrong ;)

cant convince me .9r = 1 cos it doesnt pure and simple.

So if God himself came down from "On High" and you don't beleive him, I think that puts the end to anyone listening to your opinions :)

Harley, another post which was well worth the read :)

ok then can you put 5x through the same equation then where x = 0.9r so i can see how it again gets to x = 1

Perhaps if you'd told us that you were going to be this close-minded in the beginning, you'd have saved us all a whole lot of time.
 
I agree 0.9r = 1, as it's been proven, and i agree with and understand the proof.

Just to be awkward though,

If someone was to draw an accurate graph of 0.9r, surely it would never reach 1? :p

If he'd have stayed out of the thread even more time would have been saved.

Build up 5x by working out 0.9r + 0.9r. You'll find its 1.9r or 2. Then when you add another 0.9r to that you get 2.9r or 3 etc etc. You'll find 5x0.9r = 4.9r.

take numbers out side a maths problem ok everything numbers related is maths. but view it as a wider problem .9r in anything else apart from that stupid equation does not = 1.

Nowhere have i said that .9r doesnt = 1 in that equation

what ive said is in the reall world .9r does not equal 1

and that the maths model as some one says is made by humans and is flawed in some aspects to make it easier.

The bit in red says that you can't subtract from both sides of an equation and it will still be true.

eg.
2x = 5
So according to what you said, 1x = 4 right?

But it's clear to me in the above example that X = 2.5 because X is not a number, it's a factor and so can not be treated as number.
