    well 0.9999… is actually 1 because

    x = 0.9999...

10x = 9.9999...

10x (9.9999...) - x (0.9999...) = 9

9x = 9

x = 1

so 0.9999... is 1

      This is muuuch better demonstrated by

      1/3 = .33… 2/3 = .66… 3/3 = 0.99…

      “Repeating” matters in approximations

      Yes, but 0.99999999999999999999 isn’t 0.999… and therefore not 1, so it’s still wrong.

      your 4th line reads as 10x^2 - x^2 = 9

        You know I didn’t mean it like that, but you are technically right.

      First thing that came to mind was this video by SingingBanana.

      Great maths channel and he is a frequently on numberphile as well.

      0.999… is lim(1), not 1.

        1 is a constant so lim(1) = 1
