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.

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!

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.

>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

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.

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.

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.

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
