If you write a number as the former, you imply the number terminates after some infinite amount of decimal places back. By definition, a number extending to infinity NEVER terminates. Thus the proof of convergence for 0.999 = 1 holds.
 >> Anonymous Sun Dec 24 16:25:47 2017 No.9390993 We need a base 18 for decimals to et past this logic problem of infinite repeating single digits like 0.333•••I've proposed this a couple times but just keep sharing it01a2b3c4d5e6f7g8h91/3 = 0.c, where each lower letter represents and infinite single decimal. Its important to make this distinction cause 0.3••• is as different frm 0.3 as 0.3 is from 0.4, as to say that 0.3••• is a unique number to perform arithmetic on, thus would make more sense to have its own symbol like 0.c 0.3 × 4 = 1.20.33 × 4 = 1.320.333 × 4 = 1.3320.3••• × 4 = 1.3•••Logic would dictate there would be a 2 at the end of that repeating sequence of 3's but there never is.a = 0.111•••b = 0.222•••c = 0.333•••...h = 0.888•••So thaht 0.c × 3 = 1.0 easily, and provable by counting on the number line of 0abcdefgh. 0.c as the analog for the repeating "3" gives us a base0.c×3 = 3×3 on the decimal number line or 9 countsabc def gh0 <- 0, we hit 0 and count up a whole = 1.00.c×4 = 4×3 or 12 countsabc def gh0 abc <- c, we hit 0 = 1.c

 >> Anonymous Sun Dec 24 17:29:21 2017 No.9391092 >>9391040The extra numbers of abcdefgh would only be used for the decimal point, so really it's just an extension of base-10, the one everyone uses. Its nice that 0.333••• is 0.1 in base-3 but no one uses base-3. The problem isn't the base, the problem is how to interpret repeating decimals in a base. 0.3 with a hundred, a thousand, even a million 3's after it, is a literal different number than 0.3•••, as the finite limit of 3's in the non-infinite-repeating case eventually allows base10 arithmetic to be performed.For example:0.3 × 12 = 3.60.33 × 12 = 3.960.333 × 12 = 3.9960.3333 × 12 = 3.99960.33333 × 12 = 3.999960.333333 × 12 = 3.999996which leads to the faulty logic of0.333••• × 12 = 3.999•••6where base-10 arithmetic fails the repetiton.

Pi has a seemingly infinite amount of non-repeating decimal places, but "infinity" itself is not a property of pi, because infinity is a concept and not a number, no more than than a Ford F150 is a number, or a plastic bag is a number. You do arithmetic on numbers, and using infinity in arithmetic leads to useless results, because infinity is not a number but instead a vague, undefined amount of something, much the same as trying yo determine the numerical value of "some" or "a lot".1÷3 = 0.3••• this is true3÷3 = 1.0 this is true0.3••• × 3 = 1.0 this is true0.3••• × 3 = 0.9••• this is not truethe idea that 0.3••• × 3 = 0.9••• extends from the FLAW of thinking "0.3•••" is related to "3" for the obvious reason that both numbers contain a 3 and we assume 33×3 = 99, 3×3 = 9, 0.3 × 3 = 0.9, so 0.3••• × 3 must also have a 9 in the answer.0.333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333 is NOT the same number as 0.3•••, and it is as truthfully as different as 1 is different from 2, meaning 0.3••• is a UNIQUE number that is confusingly written using established numbers.It would be like instead of a number existing for 8, you were meant to write colon-three instead ":3" so that the number line would be0 1 2 3 4 5 6 7 :3 9, and instead of ":3" being a combined character on your keyboard where 8 would be, there is no such combination and you're expected to manually write ":" and "3" individually everytime you wanted to use the number eight. Its dumb, and as dumb as writing 0.n•••, or 0.n..., or 0.(n) or whatever the fuck you do, which is where the extended decimal base-18 system comes into play to solve by ease of interpretation.

 >> Anonymous Sun Dec 24 23:53:59 2017 No.9391702 >>9391514Say we lived in a world where we had no symbol for the number three, that "3" sideways butt or catface icon didn't exist, but we wrote three as "-22-" or "hyphen two two hyphen", and more than that we did not have typing mechanisms or keyboards with the single button/key "-22-" so we would always have to type three in as I'm doing now, "hyphen two two hyphen", four distinct button inputs. This can be fairly fatiguing and annoying that there isn't a single convenient button on our keyboards in this alternate world to write the numeral three. When we do arithmetic with -22-, like -22- × 4, we know this is "three times four", therefore -22- × 4 = 12. It might frequently trip up people though, since they see two 2's where 2 still has the same meaning as a number. They might accidentally evaluate -22- × 4 = -88-, cause they know 2 × 4 = 8. We have a logic problem based on a confusing written interpretation of three.Now back to this reality, we have the problem 0.333••• × 4. We know:33 × 4 = 1323 × 4 = 120.3 × 4 = 1.20.33 × 4 = 1.320.333 × 4 = 1.3320.3333 × 4 = 1.3332And we see a pattern that multiplying 3 and 4 in this way should always result in the last number of the answer being "2"Yet 0.3••• × 4 does not equal {1.3•••2} and instead equals {1.3•••} without the 2. This is a logic problem, and the problem extends from 0.3••• actually being a unique number unrelated to 3. So in our other alternate world where there were accidents of evaluation because three was written using already established 2's, in this reality we see accident of evaluating numbers with repeating decimals because they are written using already established 3's.If we have a different symbol to represent the decimal representation of 1/3, as prescribed in >>9391507 , it becomes easy to avoid the evaluation problem of trying to add a 2 onto the end result of 0.3••• × 4 = {1.3•••} to get {1.3•••2}

Infinity is the biggest brainlet trap math ever became conflicted with, and violates every field of science including the only practical application of higher maths: computer science. even fourier transforms have limits. The full concept of infinity is only useful as a generalization for an amount, no different than "lots", "some" or "many". It doesnt define a specific number or limit and therefore can't produce a specific answer that could said to be unattainable without thinking with infinity.

Something that doesn't manifest when you deal with decimals, hence why $(\frac{1}{3}) \times 3=1$ but $0.\bar 3 \times 3$ appears to be $0.\bar 9$, just as $\frac{1}{9} \times 9$ also appears to be $0.\bar 9$ but is in fact $1$.$1$ and $0.\bar 9$ appears to be the same thing because they *ARE*. There is *zero* difference. Saying that they must be different because they appear different is like saying that $100$ and $50+50$ must be different. No. They're just different ways of expressing the same value.

Lets try this anyway:$0.\bar{9}$ + $0.\bar{1}$ = what? It equals $1.\bar{1}$ - $0.\bar{0}1$Whats $0.\bar{0}1$ + $1.\bar{1}$? It's $1.\bar{1}2$Just toss this useless shit, no one needs it. $0.\bar{9}$ is the inverse and analog of $0.\bar{0}1$ just getting by as a wolf in sheeps clothing.

Any sum trying to achieve it just ends up becoming 1 in real maths or only attempting to state $0.\bar{9}$ exists in unreal math, and no equation posits both realities simultaneously. Not because $0.\bar{9} = 1$, rather instead simply because the answer is 1 for normal number math. For example, $\frac{1}{3} × 3 = 0.\bar{3} × 3 = 1$. Evaluating $0.\bar{9}$ from this is incorrect, and just as incorrect as evaluating $0.\bar{3} × 4 = 1.\bar{3}2$Or how about this common fallacy: $x = 0.\bar{9}$$10x = 9.\bar{9}$$10x-x = 9.\bar{9}-0.\bar{9}$$9x = 9.0$$x = 1$This doesn't prove anything because it implies $0.\bar{9}$ is a number you can just come across, and arbitrarily sets it to x to perform arithmetic on it, opposed to the above example this is an unreal invocation.

Now the problem here isn't that you're trying to say $0.\bar{9} =1 && 0.\bar{0}1 = 0$, you are instead flat out denying that latter exists because it's trying to terminate the repeating sequence and place a 1 at the end. The retarded part about that statement though, is trying to equate $0.\bar{9} = 1$ does the same exact thing; you're trying to terminate the repeating 9's and make it equal to 1 whole. This is a literal paradox and you're a brainlet if you still don't understand why.Either both $0.\bar{9} & 0.\bar{0}1$ exist as real numbers, or neither do, and in either case $0.\bar{9} \neq 1$, because either $0.\bar{9} + 0.\bar{0}1$ = 1 or $0.\bar{9}$ doesn't exist as a real number.So towards proving that the only reason you want $0.\bar{9}$ to exist is to set it equal to 1, this post alone proves that $0.\bar{9}$ does not exist for that purpose.

You wouldn't say 4 × 3 = 9, would you?No? Why not?Cause four has a different symbol and different value. If you use intermantissa symbols, you no longer get confused about repeating decimals. You begin to understand that0.ב is not explicitly related to the number 3, no more than the number 4 is related to the number 3, and you then use inter-three to calculate, resulting in real actual answer 1 with no accident of believing $0.\bar{9}$ = 1 because $0.\bar{9}$ was never a factor in finding the solution.

Thats why infinity is not a number, and really shouldn't be used in arithmetic or to define a property of numbers.When i read infinite limit functions, i laugh that they surmise a result. Its the ultimate copout of lazy bullshit and is the complete opposite of "show your work". I could rewrite these functions in programming, but the diffeference there is when I go and run the prorgram i wont actually get a result back.for(n = 1; n != 0; n++){ x = 1/(10^n);}print x;this program will never print a result. It enters the for-loop and then knows its crunch time and to dedicate all time and energy to evaluating the for loop. "For n=1, while n is not 0, increment n"and then it'll calculate what is between the bracket block of { }I put my print function outside the block cause i want the answer when it has finished calculating rather than a thousand different answers every second, and this print message never occurs though because the program never leaves the loop block. It will take an infinite amount of time to count an infinite amount of increments of n, which means a finite answer cannot be calculated in finite time with aspects of infinity. You can daydream all you want as a mathematician over how the answer might or should look in your imagination, but the fact is you will one day die and no longer be able to imagine anything, and whatever infinite sequence that made up your neurons and imagination woul have come to a definite end.So yes, infinity and infinite repititions have connotations of time inherently attached to them, and is why the second example was related to the first.

As n limits to infinity the sum still equals 1. But you're trying to split up the limit by evaluating $\frac{1}{n}$ before you add them all together. That can't be done in a limit for the same reason that $1^{\infty}$ is indeterminate.
