Using algebra on an infinite series is just something I don't like to do. Infinity is not subject to the laws of arithmetic, you can "prove" anything you want by making that mistake. Not to say I disagree, I just wouldn't use that as a proof. I completely do agree .999...=1.

I don't see how that is possible....saying 1/3 is EXACTLY .333.... is not true to me... 1/3 is 3/9

.33333.... x 3 =/= 100

Algebra proof

(Moved from above to ease editing)

Another kind of proof adapts to any repeating decimal. When a fraction in decimal notation is multiplied by 10, the digits do not change but the decimal separator moves one place to the right. Thus 10 × 0.9999… equals 9.9999…, which is 9 more than the original number. To see this, consider that subtracting 0.9999... from 9.9999… can proceed digit by digit; the result is 9 − 9, which is 0, in each of the digits after the decimal separator. But trailing zeros do not change a number, so the difference is exactly 9. The final step uses algebra. Let the decimal number in question, 0.9999…, be called c. Then 10c − c = 9. This is the same as 9c = 9. Dividing both sides by 9 completes the proof: c = 1."

This is not true because if c were a variably then it may be replaced by any number. For exaple, if c=5 then 10(5) -5 would equal 9, which it clearly does not. That leaves c to be a constant, which in this case c will aways equal .9 infinity. Although 10(.9999...)-(.9999...) does equal 9, the second part of the equation does not equal 9. When you substitute c is the equation 9 *(.9999...)= 9.9999... and not 9.

while we're adding repeating decimals, whats inf+inf?

Where did I add repeating numbers????

and to answer your question, you never presented any defined values, so there is nothing to add.

What is Fraction plus fraction? U srs brah?

On the left side, you add .3... and .6... otherwise your proof does not hold true? lol

.333.. can be represented by a fraction, it is not one though. Sort of like inf/inf, it is indeterminate in that form, but it can sometimes be changed into another form where an answer can be determined. This is why i don't like these proofs, infinity does not work logically.

How are you sure that .333... + .333... = .666.... add up each digit in that decimal until you reach the end, I'll ask later and you will respond "I'm not done adding yet." This will go on for, well, an infinite amount of time. Infinity does not follow our laws of arithmetic.

Well then this is a very weak proof, if you are only assuming it to be true by following a pattern formed by two numbers. Two data points always form a line brah, doesn't mean the next one will follow suit.

Again, I agree .999...=1, but I don't like a lot of the "proofs" thrown around.

Oh lawd not this s*** again. The difference between this and the 2/288 s*** is that, at least with that one, it was all about how the problem was read. With this one, if you don't think .9 repeating is equal to 1, you simply don't know math.

Using basic math logic: if a = b, a * c = b * c

and knowing that

1/3 = .3..

let's see

1/3 * 3 = 3/3

.3.. * 3 = .9..

therefore

.9.. = 3/3

It's not that hard.

He did not, but the reasoning you were using was a little flawed in my opinion. You're teacher was definitely not lying, lulz. .99... does equal 1, it's very simple calculus. But, a lot of people here just don't understand the concept of infinity and why it cannot be treated as a real number. When putting it under the constraints of arithmetic, you are doing just that.

1) Take decimal series expansion of .9999999...

2) Find geometric factor

3) prove by demonstrating geometric series convergence

4) post on world of warcraft forums for 100000 pages of flaming

In all seriousness, I have asked 2 PhD profs out of boredom over the last few years and both used the exact same geometric series proof.

For any person who believes it does not equal 1 then I ask you this: define a real number x in the interval .9999... < x < 1 in order to contradict the proofs given. .999999... = 1 for simplicity sake more than anything else and primarily applies to the most accepted number systems we use. Unless we have some e-PhD's in the misc who use extremely advanced counting principals like hyperreals there is absolutely no reason to debate otherwise.

0.99999999999999999 != 0.999... (recurring)

0.999... = 0.999... = 1

x = 0.999...

10x = 9.999...

(BOLD!1!!!1!!!1!)10x-x = 9.999... - 0.999...(BOLD!!!!111!1)

9x = 9

x = 1

You can´t really do that bold part can you seņor curator. Pleas step over here.

Ah wait nevermind, think you can now.

0.999... = 0.999... = 1

x = 0.999...

10x = 9.999...

cooooooooooooooooooooooooooooooooooooooooooooooooo ooooooooooooooooooooooooooooooooool.you have .9 to 5 decimal places. As .9 approaches infinity number of 9's, the number converges to 1.

.9...+.9... does in fact = 2 because the number is so incredibly arbitrarily close to 1

Edit: if an algorithm were built to further prove that taking an infinite sum of .9999.....will yield 1+1+1+1+1.....because the number of times .999..... is repeated will approach infinity while the number of 9's also does.

now i don't really know much about calculus.

but i don't think it is even possible to ever come across .999 repeating in any formula or function, without using repeating decimals in the first place

if so, then it does not matter if .999 repeating = 1 because .999 repeating would be a pure abstraction.

For 2 numbers to be different there must be a number in between them. There is NO number between 0.999... (repeating) and 1.

that's the proof I always use.
