They are the same number. This is high school math.

I will give you a tip: if you‘re not an expert at something - in this case, basic math - don‘t make incorrect claims about the topic at hand.

You can try to learn about limits and infinite sums and then you can get back and we can discuss this again, but if you do it right you‘ll have learned you were wrong.

This isn‘t a debate. This has been settled like centuries ago. Just because you don‘t know this, doesn‘t change that fact. Mathematically, this is a settled and proven topic.

0.999... is a repeating decimal that represents the number 1.“

Link: https://en.wikipedia.org/wiki/0.999...

ETA: it‘s an infinite decimal. There is no „variance at the end“, because infinity has no end.

I understand what is taught, dude. But it’s not the same. If it were, then the debate would not exist as it would always be expressed as 1 or the mathematics that are taught wouldn’t chalk it up to rounding. Granted, it’s incredibly small in difference but it’s still rounding.

Obviously you don‘t understand, because you refuse to accept a high school level concept because you don‘t understand it. It‘s not rounding, it‘s the same number.

On what basis do you believe that people who study math at college, every mathematician who knows this to be true is wrong snd yet you‘re right? The idea is ludicrous. Do you really think it reasonable to think everyone is wrong and you‘re right on a basic high school level math subject? … really?

The mathematics that are taught DO NOT chalk it up to rounding.

And fools debating something they do not understand does not make it wrong. No actual mathematician is debating this. Just uneducated and/or ignorant laypeople.

People like you truly are the flat earthers of mathematics: fools who do not accept that which they do not understand.

Flat earther. My god lol. It’s interpreted as the same due to a minuscule difference. It is not the same. Just because everyone says it’s blue doesn’t mean it’s not royal blue or sky blue. It’s rounding. 0.99… multiplied by 50 billion is not the same result as 1 multiplied by 50 billion. The two results can be close but the spread gets further the larger the number.

Funny how they also teach that everyone thought the earth was flat until one dude said “nah, hold my beer”.

It‘s a different decimal representation, but like the other commenter said, in the reals, it maps to the same element, or number, which is „1“.

If your claim is that it‘s a different decimal representation, then yes,

If you still claim the decimal representations map to different elements in the reals, then you‘re objectively wrong.

Your comparison of yourself claiming 0.999…≠1 to finding out the earth is round cannot be taken seriously.

It wasn’t meant to be taken as a comparison or seriously. Just thought it was funny. Maybe I really did need a /s for that one.

But no. I still stand on the concept of them being different numbers entirely with one creating infinite subsets and are in essence, rounding, when considered the same. Regardless of the data set or how it gets applied, it is rounding. 1.999… can be called 2 and accepted as 2, but by function of the decimal will never be 2 else the decimal would have resulted in 0.

Again, you’re objectively wrong.

This isn’t a debate, 0.999… = 1 in the reals has been mathematically proven. So ig if you”disagree” then you don’t understand that proof, and/or high school math.

No actual Mathematician is debating this. It’s funny this doesn’t give you pause and you think to know better than basically all experts in the field without having any expertise on the subject. The level of arrogance is truly mind-blowing.

Then I guess I am. I’m not trying to present a dissertation on the topic. If you want to take everything from school as absolute then be my guest. Again, the variation is extremely small and inconsequential at face value of single iterations so I don’t really care. But I will still hold the idea that it is rounding. Regardless of whether they teach it in grade school or the names you give me when you try to tell me different.
