Does .9 infinitely repeating equal 1? At first glance, one might say, "Of course not!", but hear me out. I asked my genius math teacher the same question, and he though about it, then wrote a long equation apparently proving that they were the same number. I have since then forgotten the equation, therefore, forgotten how he arrived at his conclusion. A fellow classmate said he would argue to the death that they were not, but his opinion changed upon reading the teacher's equation. My way of thinking it is this: If 3 x 1/3=1, and 1/3= .3 infinitely repeating, then .3 infinitely repeating should equal 1. But if do the multiplication, each individual 3 would become a 9, so the answer is also .9 infinitely repeating. So 1/3 x 3= 1= .3 infinitely repeating x 3= .9 infinitely repeating. So 1= .9 infinitely repeating. But to say that two different numbers, excluding fractions, etc, can equal the samething doesn't seem right. So, are they or are they not equal? (link)

hmm . . . don't think they're equal, but I'm not a math teacher. In class my math teacher was talking about the infinite number of numbers between any two numbers thing (O_O) and she told us about the guy who came up with that.
His friend thought he was stupid, so told the friend to walk halfway across a room. Then halfway across the remaining half. And halfway across that. And so one and so forth.
Stick your .9999999 infinite repeating question in there, and I don't think they're the same at all.
