I didn't realise you had such a mathematical genius. If only you'd said you rival Stephen Hawking, we'd have all shut up immediately.

*bows down before his new God*

Please oh Great One, impart on us your other nuggets of wisdom!

Any proofs you guys come up with you must therefore believe to be true either before you do them or after the equation has been written so why do you believe 0.99r = 1

There's nothing in between 0.9r and 1.

As I've been saying for the past several hours!

Anyhow, fascinating as this has been, it's approaching 2 AM here, I have school tomorrow, and I have to get some sleep. Night all!

You cant do the 0.0r1 trick coz there no such number

U cannot put that 1 because the r before it signifies that those 0s will never ever finish. ok ?

thats why you are wrong.

Then I will say that you cannot write 3.333 on your next maths paper when diving 10 by 3. Simply because 3.333 is not the same as 3.3r.

How do you like them apples?

Now what if I inadvertently made a mistake in my counting, and there is only £99,999,999,999.99 worth of pennies there.

You're trying to compare discrete pennies with a continuous number system... not gonna happen, is it?

Recurring decimals are ways of describing fractions, simple as.

and that is the self and same reason why normal people dont listen to mathmaticians. Because we think them to be illogical and that you cant listen to or understand logical argument.

And still no one has answered my question.

Who said 0.99r = 1 who proved it and why did they believe it to be so ?

so ?

that still proves that 0.9r and 1 are two different numbers they are not the same number.

Maths for the sake of maths. Lots of top mathematicians love it when they discover something new, and it has no bearing on reality. It stays 100% pure pure maths, and isn't turned into "nasty" applied or stats.

Are they going to count them all? What if they make an error during counting? They could employ a computer to count it by feeding a penny through at a time, but it could make an error and accidentally feed two pennies through by accident!

It might be so very very very close to the number, but it is not the number.

For all intents and purposes, the number is "infinity", since it cannot be counted, or it could, but it would just take so damned long.

Just like for all intents and purposes we call 0.9r 0.999 or 3.3r 3.333. If we tried to count it (Which I'll agree is impossible, but IF we tried), it would take so damned long.

When doing maths people trim these "recurring" numbers down to a number which makes more sense when writing it down. If you dont, then the number is irrelevant in real life as it cannot exist.

I think this is where a lot of people are going wrong. Thinking that infinity is just a 'really big number'

You cannot count to infinity, no matter how much time you have.
Get the fastest computer in the world to count until the end of time and you will still be no nearer the end than you were when you started.

If you believe you could eventually reach infinity then this is like believing you could set off walking around the world and one day you would come to the edge.

Given maths is the ultimate expression of logical argument, I find that a bit rich. You ignore proofs (about 8 of them at last count!) again and again, and explainations and say we're illogical? I have yet to see a completely logical argument from you yet ;)

I dont think you are understand infinity, which quite necessary for comprehending why 0.9r = 1.

0.9r is not infinity, not even close, there are an infinite number of 9's after the decimal points but it is still not infinity.

haha stats, think of a number, add some other number, take away the standard deviation and you have....another number

Erm it does have bearing. that computer you are using now works on principles in maths.

All the technology u use works because proofs in maths are infallible. maths has bearing in real life.
 
Would suggest going to the party and accepting that sometimes not everyone is going to agree with you ;)

You obviously don't beleive in the expansion of human knowledge then. I pity that you don't feel there is antyhing beyond materialistic gain.

75% of this "pointless stuff" is the reason you have electricity, a PC, heating, a car and enjoy satellite TV. Without maths we'd all be living in the 1500s at the moment:)

Not true. Maths always has a purpose. Whether to calculate the gravitational pull of the sun, or to calculate how long it would take an apple to hit your head if I were to throw it to you. Maths helps physics, physics helps maths, and in turn they aid us in life.

Maths always has a purpose.

Your not getting my point. We expand in human knowledge in order to aid us in and/or help us understand LIFE.

its not a case of agreeing that 0.9r = 1 it is true, you simply cant say, i disagree that that is true with no proof, when there is clear proof it is true. and something cant be true and not true at the same time (that i know of)
