Pseudomathematicians invented the symbolism out of their laziness. 0.999... simply implies a number whose fractional part comprise 9's the number of which approaches infinity. When 1, 2, 3, 4, ... shows up, no one talks any limits, so why should things be different with 0.999...?Not only the kids, I'd say. Pseudomathematicians too.
Again, stop simply trying to posit aspects of your own failed reasoning onto others.
Here is an example of the fact that we may not see every arrangement there is, coz we can't be "omnifocused."
Doron, [text]
So you began to write a short letter/post to Doron. The nature of the text depends on what you want to say and the name that you've already written doesn't affect the composition of the text. But it can. Doron makes often ascriptions that are not immediately clear and here is a model of such.
Doron, 14_5
Assuming that the numerical assignment isn't random, the possible logical explanation to the choice of the numbers is that it applies to the last letter in the name: N is the 14th letter in the alphabet and the 5th one in the name. So substitute "text" in the brackets with both numbers:
Doron, [14_5]
Now you respond in kind. Would Doron be able to decode the symbolism, which says to look for a sentence that is made of 14 words where 5 of them include letter N? If he does, would you be able to compose such a sentence given the numerical restriction?
Wow! That was fast.
![]()
When a real number represents a measurement, there is always a margin of error. This is often indicated by rounding or truncating a decimal, so that digits that suggest a greater accuracy than the measurement itself are removed. The remaining digits are called significant digits. For example, measurements with a ruler can seldom be made without a margin of error of at least 0.01 meters. If the sides of a rectangle are measured as 1.23 meters and 4.56 meters, then multiplication gives an area for the rectangle of 5.6088 square meters. Since only the first two digits after the decimal place are significant, this is usually rounded to 5.61
Pseudomathematicians invented the symbolism out of their laziness. 0.999... simply implies a number whose fractional part comprise 9's the number of which approaches infinity. When 1, 2, 3, 4, ... shows up, no one talks any limits, so why should things be different with 0.999...?
P.S. Why is this thread in the "Religion" subforum?
It's "Philosophy"; well, it certainly isn't mathematics.
Really? But I read some maths here and there. How is it philosophy?
And I know 0.9(bar) = 0.999... = 1. That's for sure. I'm just saying only pseudomathematicians or kids/students say it's not.
I don't get why it is "laziness", but well, that's not really important. And I know 0.9(bar) = 0.999... = 1.
Many are persuaded by an appeal to authority from textbooks and teachers...
The reason why you "know" that 0.999... = 1 is simple:
The symbolic rendition 0.999... = 1 is a short of the full representation that starts bellow:
0.999... = (10n - 1)/10n where n → ∞.
When you substitute n in the formula with 1, 2, 3, 4, the result is 0.9, 0.99, 0.999, 0.9999 respectively. Obviously, substituting n with positive integer that approaches infinity results in a number that can be rendered as 0.999.... The ellipses indicate that the 9's will repeat ad infinitum. This number is always smaller than 1, but . . .
lim[n → ∞] (10n - 1)/10n = 1
The above identity says that the limit of the expression equals 1; it doesn't say that in some moment, as n approaches infinity, 0.999... suddenly becomes identical to integer 1. But in practical applications, such as in calculus, various limits are treated as an exact representation of the results that involve numbers that are approaching certain values through a convergence, but never reach them. The margin of error is simply "infinitely small", and can be safely neglected. No one ever went wrong by doing so.
There are surely kids out there who now believe that 0.999... as a number where the 9s repeat infinitely doesn't simply exist and that Doron has been right after all saying that a straight line has "blind spots" -- that there are segments on that line that cannot be covered by points.
The reasoning of Limits can't comprehend the place value system as numbers, because it has no understanding of different levels of existence between Emptiness (that has no predecessor) and Fullness (that has no successor).
Organic Mathematics shouldn't rely on the obsolete traditional approach; it should come up with its own version to account for the approximate rendition of number Pi, right?
epix said:The limits are essential in calculus. Without them, there would be no calculus and without calculus we would be on the same scientific level when there was no calculus.
Some reading problems?
The considered number is smaller than any arbitrary number of (0,1] AND it is also > 0.
In other words, this considered number is not 1 AND it is not 0.
Unless it is clearly written that the considered member is smaller than any arbitrary number of (0,1], where 1 is one of these arbitrary numbers, and you simply can't get it.Again the interval (0,1] doesn’t restrict a member of the resulting set from being 1 while the interval (0,1) does.
The greatest and defining difference between Organic Mathematics and contemporary mathematics is that the former is purely intuitive and the latter is purely analytic.By the way, OM is different than the notion of Infinitesimals ( http://en.wikipedia.org/wiki/Infinitesimal ) or the notion of Non-standard analysis ( http://en.wikipedia.org/wiki/Non-standard_analysis ) which uses Infinitesimals, because the Infinitesimals are still taken as strict numbers , such that there is a strict number h that is smaller than all positive 1/n, and 1/h > any positive R member.

Calculus doesn't avoid handling values that approach zero -- it just handles them properly. You are under a wrong impression that inWhat is called traditional calculus, is simply a system that uses techniques which avoid non-strict results.
The alleged shortcomings don't seem to have any impact on the ability to find the derivative of a function, for example. Why don't you identify a particular problem that only OM can deal with? "Emptiness" and "Fullness" never appear other than names -- they can't be spotted in the graph, in algebraic terms, equations... They only contribute to the solution ofLook, for example, at Relative Set Theory http://maths.york.ac.uk/www/sites/default/files/Hrbacek-slides.pdf .
This approach uses also different levels of existence, but it still misses the fact that a given level can't completely be defined by some previous level, because it does not understand Emptiness (that has no predecessor) and Fullness (that has no successor).
In fact your own assertions indicate that a location must be a point.

You should elaborate further to highlight the difference between the complex and non-complex case.Any given existing thing between these totalities has predecessor AND successor, such that there are strict ( for example: PI() ) or non-strict ( for example: 3.14…[base 10]() ) things that appear as non-complex ( for example: ∞( PI() , 3.14…[base 10]() ) ) or complex ( for example: ∞( PI(3.14…[base 10]()) ) ) forms.

The Man said:Location a long 1() is exactly 0().
"≠" still isn't a location.
Are you claiming that any location “a long 1() is exactly” a point?
No, it is about (nested AND complex forms) OR (non-nested AND non-complex forms), where the considered things are strict ( for example: PI() ) or non-strict ( for example: 3.14...[base 10]() ).The only discernible difference is the placement of the parenthesis
Yes, any given exact location along 1() is 0().Are you claiming that any location “a long 1() is exactly” a point?

fify.
There is no exact location on a line where there is no point, and ≠ is such non-exact location on a line, which exists between any given arbitrary pair of distinct exact locations (arbitrary pair of distinct points).Right, so there is no location on the line where there is not a point?
No, it is about (nested AND complex forms) OR (non-nested AND non-complex forms), where the considered things are strict ( for example: PI() ) or non-strict ( for example: 3.14...[base 10]() ).
According OM, 3.14...[base 10](PI()) is false expression, where PI(3.14...[base 10]()) is true expression.
So if I'm not sure, I can use the identity 1pi(radian) = 180(degree) to avoid the aproximate form pi = 3.14..., right?
That's not true. The function f(x) = (x2 - 4)/(x - 2) is not defined for x = 2, so you can't see the point drawn at that exact location.There is no exact location on a line where there is no point, and ≠ is such non-exact location on a line, which exists between any given arbitrary pair of distinct exact locations (arbitrary pair of distinct points).
