The thing is that if you try to divide 1 by 3, you get .3, as if dividing .9 by 3, and .1 in memory. Now you have to divide that by 3, and get .03, as if dividing .09 by 3 and get .01 in memory. This repeats, forever, because you can never divide 10^n by 3 and get an even number. That's the proof that .(3) = 1/3.

3/3 = 1

1/3= .33333...

Therefore, (.33333333....) + (.33333333....) + (.33333333....) = (.99999999...) = 1

This post? 

Yep, and both calculator proof posts as well.

If 0.(3) is approximately 1/3, then why does simple arithmetic prove otherwise?

n = 0.(3) [1/3]
10n = 3.(3) [3 1/3]
10n - n = 9n
3.(3) [3 1/3] - 0.(3) [1/3] = 3
9n = 3
n = 3/9 = 1/3
0.(3) = 1/3

The point is, you need infinity 9's, there simply aren't that many 9's.
No matter how many times you write a 9, you will never get infinity 9's.

0.999... != 1
QED

But.... 0.999... means 0.999 followed by an infinite series of 9's.

It. Is. What. It. Means!

If you don't like the convention, don't use it! Write as many numbers as you like. But don't use the convention to mean what you'd like it to mean!

Well, then, what keeps you from keeping 0.(9) as 1?

I don't know but
1/3 does not equal .333..... 

1/3 approximately equals 0.333.... though

Then STFU. Noone was asking you about 0.(3). But, if you want to pretend to be clever, even 0.3 is an approximate value for 1/3. For that matter, even 0.5 is, but the error is 50%

Again: look at this link.

It's not an assumption. It's a convention!

Quote from: wikipedia
For example, the decimal representation of 1⁄3 = 0.3333333... (spoken as "0.3 repeating") becomes periodic just after the decimal point, repeating the single-digit sequence "3" indefinitely

In other words: if you want to talk in the same language, you don't have a choice but to have .3... = 1/3. If you don't accept that... well, you're Simply.Not.Speaking.The.Same.Language!

The proof is right there, you idiots. Defeat my proof with a mathematical and not technological proof, and I will admit defeat. Until then, I win.
Now try doing it with a real calculator (A CAS based one) and see what answer you get if you tell it to give you an exact answer.

This is the problem with teaching kids math by only using calculators

You can only get an approximation when using digital computations as explained before: There is not enough memory to store the infinitely long sting of 3's. While 1/3 is an exact, it is mathematically equivalent to .3333333..., because even though 1/3 is more exact, it is a function, and it's result is an irrational number. You can express irrational numbers in visually rational way, but it doesn't negate the fact of their equivalence. 1/3=.333333... no matter how you try and deny it. The computer's software however are designed and coded correctly to understand this and not produce an error in the output, and thus, based on real mathematical rules, will continue to provide extremely accurate results, even correct one's when dealing with such irrational numbers.

When I perform (1/3)+(1/3), I get an approximation as well, when traversing the equation the long way on the calculator, but when I add the last (1/3) [so that my button sequence is (1/3[which =.3333333333...]+1/3[which then =.66666666667]+1/3)] I get 1.

When (1/3) = .3333..., and we know that (1/3)*3=1, then we must deduce that .9999... = 1. Basic arithmetic, and backed by a calculator. Learn the rules of simple math's and you should deduce the same instead of being a stubborn calculus nerd who want's to think different.

.99999...=1=(1/3)*3

Still not defeated, next.

To simplify:

(1/3) = .33333333...
(1/3)*3=1
(1/3)+(1/3)+(1/3)=1
(.3333333...)+(.3333333...)+(.3333333...)=1
(.3333333...)+(.3333333...)+(.3333333...)=(.999999...)
(.9999999...)=1

Remember, basic math's.

Dude. Look. At. My Link.

Quote from: Wikipedia
The decimal representation of a real number is called a repeating decimal (or recurring decimal) if at some point it becomes periodic: there is some finite sequence of digits that is repeated indefinitely.

It's not repeated infinitely, that's true. It's repeated indefinitely.

But your question is as absurd as asking us to write out an imaginary number (i, for instance). Do you know i^2 equals -1? It's a convention, necessitated by the behavior of certain numbers in mathematics. It. Is. A. Convention.

Any mathematician understands what it stands for. It doesn't matter that you can't write it out any other way. It's a useful concept. Nothing more, nothing less.

When you ask us to write it out, it's simply proof that you don't understand the underlying concept.
