 >> Anonymous Thu Aug 27 14:12:35 2020 No.12055012 I don't really get this. 1/3 would only work in a number system based around 3's. In a 10 digit system, the best you can do is an approximation, which is .333 to infinite. It should be understood that .333 is a representation of 1/3, but if you're interested in being exact, 1/3 should be used. There's a reason we use different systems, as they allow specificity and flexibility depending on the task.

 >> Anonymous Thu Aug 27 14:20:30 2020 No.12055038 >>12055012I would say this is incorrect. The decimal notation we were taught in school allowed for putting lines above digits to indicate them repeating indefinitely, and this allows you to exactly represent fractions like 1/3 (as 1.3 (repeating the 3 indefinitely)) and 1/7 (as 0.142857 (repeating the 142857 indefinitely)). However it should be noted that in this system, representations aren't unique, so the real number 1 can be represented both by 1 and by 0.9 (repeating the 9 indefinitely)

A base 3 system could represent 1/3 accurately, but then a vinculum would be require for other fractions that don't work in base 3. What really matters is that people agree about the representation, which they generally do unless they feel like arguing on /sci/.

 >> Anonymous Fri Aug 28 16:31:44 2020 No.12058980 >>12053975Against my better judgement (and also because I'm bored) I will answer these. The first one, (0.999...+1)/2 would be great if you could actually produce such a number. As it stands, no decimal can conceivably be imagined that represents this. The argument also goes more like this: 1-0.999... is less then every single rational number-since there exists a rational less then a real[simply take a new number by a termination of that reals decimal sequence], then any real number which 1-0.999... supposedly is, would mean I can find a rational less then it-in turn, 1-0.999... is not less then every rational, a contradiction. I would like to see you worm your way out of the properly stated form of this proof rather then the strawman.The second one is to ask what it means for a number to correspond to it's decimal expansion: the answer is the limit of the partial representations of the decimal and in that case 1/3 certainly equals 0.333... To ask such a question without even being clear how the decimal sequence (0,3,3,3,...) relates to the number 1/3 is a pointless exercise. 0.333... isn't a decimal approximation-it is the true to goodness calculated value of 1/3-at any given termination at point n,The third one, from a formal perspective, is a bit iffy [namely, on the multiplication by 10-this needs to be better elaborated on[. However, to claim 9.999... - 0.999... =/= 9 is to reach mount stupid, since this is how decimals have always worked. Also, your DIVERGENT series is a red herring since these series are convergent, absolutely so, in fact. The sum of two convergent series is the series of the summed terms-this is a basic proof.Basically, fuck off and learn math. All your tripe objections are easily, easily answerable if you actually care to learn.

The totality of the sequence of digits to represent them in decimal format are both infinite.The decimal expansion isn't a real number but a sequence-there is an assignment to a real number by its infinite series as a decimal, which is defined as a limit.This isn't even comparable (if you write it out in full you lazy bastard) to your 1/x case, and you still get it wrong since lim x-> 0 1/x isn't inf, only if you approach it from the positive.Pretty rich for you to tell someone to 'go back to fundamentals'. This is real analysis 101.

I will simply point you to a proof that for every two real numbers, there is a rational inbetween: http://fulviofrisone.com/attachments/article/453/Principles%20Of%20Mathematical%20Analysis%20-%20W.Rudin.pdf#page=18.Alternatively, another way to view it is that the rationals are dense in the reals[simple fact of topology]-if 0.000...1 and 0 don't have a rational inbetween, then clearly the interval (0,0.000...1) consists of points in which are not rationals nor are limit points of rationals, a contradiction..
 >> Anonymous Sat Aug 29 03:10:19 2020 No.12061582 >>12061580Also, it should be clear that '0.000...1' means a bunch of 0, and THEN a 1.[the sequence is of order type w+1] '0.999...' means a bunch [countably infinite] number of 9's, there is no 'after'. [sequence of order type w] Summing these in the only meaningful way would give 0.999... 1 [again, this is assuming 0.000...1 means anything which there is no system I am aware of that it does]. As you might have noticed, this does not produce 1....And to that, it should be noted that '0.000...1' has no meaningful definition. For a positive real number r, let a_0 be largest integer not 0 such that. r-a_0>0, then a_1 largest integer such that r-a_0-a_1/10>0, and so forth. This defines a sequence (a_1,a_2,...) called the decimal expansion. So, you have the 'decimal' (0.000...1), for what value of n in the sequence do you get this 1? If you were to actually carry this out for 1-0.999..., you would get (0,0,0,0,...), which, as you may have noticed, is just a string of 0's. And, the infinite sum a_0+a_1/10+a_2/100+... is equal to r, as the limit of the partial sums (the definition of infinite series) is r by the above algorithm. So the real number defines the decimal and vice versa-so since we do this for 1-0.999... and get decimal (0,0,0,...), what real number do you think we'll get? I am putting my money on... 0.Also, 0.333... is 1/3 and it always has been and always will be. It's you whining against pretty much the most obvious concepts of mathematics. The left is infinite series with terms 3/10^n, which sums to... 1/3. What do you think it sums to, it is a geometric series so should converge to some number, if it isn't 1/3 done by basic plug and chug, what is it? Again, learn real analysisAnyway you cut it, you are wrong from practically every angle imaginable

Grab paper and pencil and try doing this and let me know exactly where I mess up because I think I've made it stupidly clear. Please be very specific, not some vague stuff about 'you set sum equal to limit', point to a specific logical fallacy.Forget about decimal notation. Based on the above process, call the decimal of that number the sequence (a_0,a_1,a_2,...). It has, as of yet, no connection to a specific real number. There is a real number r, and an algorithm that produces the above sequence.You now DEFINE a_0.a_1 a_2 a_3... as this real number by what I did above-as the limit of the given series. Still following? 0.333... is a NUMBER, and 0<0.333...<1-it is less then a FINITE number and therefore is finite. It isn't 'oo'-now, the amount of non-zero numbers in the sequence IS infinite, but that isn't what we mean when we say a number is infinite. And, the algorithm for numbers with terminating decimals still is infinite, just with redundant zeroes.0.333... is therefore DEFINED to be the series 3/10+3/100+... which is DEFINED to be its limit of the partial sums. The limit of its partials sums is the number 1/3, so 0.333... is by definition 1/3.

The true interpretation of the real numbers is as equivalence classes of Cauchy sequences. The two sequences in question are[eqn] 0.999\ldots \sim (0, 0.9, 0.99, \ldots) [/eqn]and[eqn] 1 \sim (1, 1, 1, \ldots).[/eqn]As sequences, we see that they are not literally equal. However, both belong to the same class of Cauchy sequences since for any $N \in \mathbb{N}$, there exists some $K \in \mathbb{N}$ such that for all terms beyond the $K^{th}$ term, any values from either sequence are withing $1/N$ of each other. So as sequences, no, but as real numbers (equivalent sequences), yes.

So one can no longer do arbitrary operations that would be valid in a field wihtout being careful.>>12065847Compactification is no pseudo-mathematics, retard. It has a real valid point when talking about topology.
