1/3=0.333.... here, 0.333... is an incomplete expression representing a state of 1 being constantly divided by 3. Similarly, (1/3)x3=1=0.333...x3=0.999... and 0.999... is now also an incomplete expression for 0.333... being constantly multiplied by 3. It's just a math version of word games. It simply shows that the language of math isn't perfect. I don't get how brainlets still don't understand this.
