0.999... != 1 - Prove me wrong.
The difference between them is infintesimal, the conceptual "smallest possible VALUE", 0 doesnt have a Value btw

>> No.10416414

What do you mean when you write 0.999...?
Have you learned yet that 0.999... is the decimal expansion of the real number 1? If not, then what grade are you in? 5th?

>> No.10416438

let x = 0.999...
9x = 10x - x = 9.999... - 0.999... = 9 <=> x = 1

The idea is that 0.9... exists in the set of 0 not 1. I know that one cant >pinpoint< the difference between 0.9... and 1, so the idea is to create a conceptual infintesimal.

>>10416438
The problem is that 10x of a finite number results in a loss of 1 decimal place, and 9x is 8.9..1
How can the irrational 10x0.9... retain infinite (or equal) decimal places to 1x0.9...

Reminder that infinitesmimals aren't numbers. Reminder that if the difference between two numbers is 0, they are are equal to each other. Reminder OP is a fag.

Find me any r

>>10416502
You are confused. 0.999... is not an irrational number. 0.999... is the number 1.

1/3 = 0.333...
Surely you don't believe 1/3 is an irrational number?

True story - Chrischan used to sit in the lobby of my college's library and loudly play video games while wearing his signature horizontally striped shirt and his homemade Sonichu pendant. He gave my girlfriend a letter that asked if she would be his girlfriend. She threw it out and I never forgave her for that.
