    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
