The problem is that
1/3 doesn't equal .3333333333333
2/3 != .6666666666666666666

Slice something perfect 3 times and it has a very well defined edge and size. It's like that arrow problem that never reaches the target because it keeps closing "half the distance." It's bullshit. Using infinitely repeating decimals is the same as a 3 year old saying unicorns are real to justify why the living room looks like it was ran through by a horse.

This is not possible.

I appreciate your take on this. However, I can’t help but think how crazy this world is that you even have to argue the point. It’s like the fact that we even have to have debates these days about how many genders there actually are... or whether Boy Scouts should include girls... or whether illegal aliens should be protected under US law. I think basic logical reasoning is a lost art! I already knew 0.99999999.... is not equal to 1.... because it’s not! Simple reasoning! However, the fact that this false premise is even being circulated, and apparently some people lack the sound rational judgmental faculties to see the obvious flaw in the logic, reminds me also of George Orwell's 1984. For many years, there has been a systematic move by the "politically correct" nazis, to wear down our common sense and reprogram our thinking abilities via what Orwell described as "New Speak". Now with math, apparently this 0.99999 = 1 is reminiscent of Orwell's "2 + 2 = 5". Careful dude, or you might find yourself facing the wrath of Big Brother!

How can I cut a number? Show me a number, and also a knife that can cut it.

>> No.11874242

What if you wrote 0.999... as the convergent sum of 0.9*10^-n (0.9+0.09+0.009....)

What is the limit of such a sum ? Sum of geometric sequence gives 1 as an answer.

Why are you gay

>Slice something perfect 3 times
the real world is made out of atoms and quarks
when you "slice something perfectly 3 times", youre just dividing a multiple of 3 by 3
you might notice that 1 is not a multiple of 3, so you cant use it in an analogy

>> No.11874250

Math is not the "real world"
Math is a tool we made up.

>> No.11874273

everyone recognizes 1 as the limit. What’s controversial is whether or not 0.999... EQUALS 1.

Stop being abusive. Suicide and mental illness is no joke.

This entirely depends on what you mean by 0.9999, equals, and 1.

>> No.11874304

That wasn't a joke. Anyone who seriously posts in ongoing decimals threads needs to die.

I hope you don't know any one with mental illness. Maybe one day you will feel the pain of losing a loved one to suicide and you will change your tune.

You are probably a child anyways, so it is pointless to discuss this further anyways.

It's an approximation you fucking retard.
It can't be exactly represented in base-10.
The use of base-10 is arbitrary.
You could choose another base and represent it exactly if you'd like.

1/3 = 0.3 + 0.1/3

In chess two very similar moves can have completely different results, to me saying 0.9999... = 1 is like saying the order of your moves doesn't matter. It's just a pseudo-intellectual flex on normies who don't do math.

>> No.11874380

can you define what exactly do you mean by the symbols "0.999..." and "1", and prove that they're distinct objects ?

>> No.11874384

Why do you avoid using the word divide? Do you believe division is a representation of anything in reality?

>> No.11874388

They are numbers that specify quantities.
You can tell whether they are the same or different based on how they look.
For example, 1 is the same as 1 because they are both written as 1.
It's kind of like putting a square block into a square hole. You just match the shapes. If you try really hard I'm sure you can do it.

The base-system is retarded for anything beyond integers, especially in decimal. We should use surreal numbers instead when denoting non-integers.

Just like infinite decimals aren't either. 1/3 is just that, 1/3. It's not .3333333333333333333..... it's simply 1/3. I don't care what base system you use. When I have 3 friends over and we split a medium pizza we each take 1/3 of the pizza, not .3333333333333.... pieces of pizza. If we did eat .33333333333... Pieces of pizza each, we would be eating infinitely smaller pizza forever!

Even the smallest particles in things have finite quantities. So defining anything finite with an approximation of infinity is false.

Holy fuck you guys are dumber than I thought.
Numbers are symbolic of quantities.
Fractions are symbolic of numbers.
It's an additional layer of abstraction.

1/3 = 3/10 + 1/30

= 0.33 + 1/300

The issue is that 1/3 can't be represented as a decimal.
If you plug in 2/3 into your calculator you'll get .666..7 as the answer that last .000...1 is inevitable.

.333 + .666 + .001 = 1
