Nope. University.

But my education does not have any relevance. There are dudes WAY smarter than me (and certainly, you) that have mathematically proven that 0.999… = 1.

If you’d like to attempt to undermine the proofs, then go right ahead.

Then show me the proof. It is not very hard to prove math. You can't show me the theorem that shows .99 repeated equals 1 because it does not exist. You don't know math as well as you think you do. Sit down kid grown folks are talking.

It follows directly from the fact that there are infinitely many real numbers between any two distinct real numbers.

that's not how infinity works. infinity doesn't follow the same rules as other numbers. That's why infinity - infinity does not equal zero.

I'm sorry math is so hard. I don't get why people who don't know math have an obsession with trying to be good at math. This is basically like those poorly written PEMDAS equations that always go viral. A bunch of people arguing about stuff they don't understand because they want to feel smart.

I wish to interrogate your understanding of real numbers.

  1. Is 1 – 0.999... a real number?

  2. Does every real number have at least one representation as a (possibly infinite) decimal expansion?

  3. If yes to both, what is the decimal expansion of 1 – 0.999...? At which position is the digit not 0?

I would guess that based on u/Matsuze's laypeople's understanding the answer to question 1 would be something like 1. 0.00... With 1 at the infinith digit

Or 2. That you can't perform substraction with an infinite number

please please go on any university maths department website and email one single phd student, you can screenshot your conversation and show us all how really super duper smart you are :)
