Why 0.9999… equal to 1
Recently, I am trying to understand better about calculus and limit. And there is a famous debate or question about how could 0.9999… is exactly equal to 1, or in other words, 0.9999… and 1 is the same thing.
It is a bit counter intuition, but still understandable.
Solution #1: Analogy
1/9 = 0.1111…
