.999...=1 btw

<p>just wanted to make it clear.</p>

<p>yeah my teacher tried to convince me of that. It's a conspiracy.</p>

<p>1/9=.11111111111111
2/9=.22222222222222
3/9=.33333333333333
4/9=.44444444444444
5/9=.55555555555555
6/9=.66666666666666
7/9=.77777777777777
8/9=.88888888888888
9/9=1? .9999999999?</p>

<p>Yeah...like 7/9 eventually goes.7777777(however many 7s)8</p>

<p>and so on...</p>

<p>x = 0.9999999999...
10x = 9.999999999...
9x = 9.000000000...
x =1.000000000....</p>

<p>x=.999999...*10=9.99999.....=10x
10x-x=9x=9
x=1</p>

<p>LOL physicslover. We have the same idea.</p>

<p>How do you make 2 = 0?</p>

<p>Cool stuff. I used to know how to make 1=0 back in like seventh grade. I've forgotten since then.</p>

<p>x + 2 = x
-x -x
2 = 0</p>

<p>actually. .999 = .999, not 1.
4/4 =1
748384575/748384575=1
but not .999 :)</p>

<p>5/9 + 4/9 = 9/9
5/9 + 4/9 = .55555 + .44444 = .99999</p>

<p>.'. 9/9 = .99999</p>

<p>Nope actually.</p>

<p>The 1=2 thing that someone brought up:
Let us have 2 integers a and b such that a=b</p>

<p>a = b
a<em>a = b</em>a (Multiply both sides by a)
a^2 = ab (Restatement of same thing)
a^2 - b^2 = ab - b^2 (Subtract b^2 from both sides)
(a+b)(a-b) = b(a-b) (Break into factors)
(a+b) = b (Divide by a-b)</p>

<p>So we have a+b = a, even though a = b. So if a = b =1, you have 1 + 1 = 1, or 2 =1. </p>

<p>Of course, it takes about 5 seconds till you see the hole in the whole thing. I'll let you figure it out, though. :p.</p>

<p>you are dividing by 0. good idea tho</p>

<p>(x+y)(x-y)/(x-y)=x+y
(x^2-y^2)/(x-y)=0, when x^2-y^2=0 ->when x=y=1, 1^2-1^2=0
btw, if x=y=1, x+y=1+1=2
therefore 0=2</p>

<p>messed up..lol</p>

<p>Haha yeah. You can't divide by 0. But most people don't catch that. :p</p>

<p>yeah... .999 does not = 1...it doesnt. honestly its kind of silly to even contemplate it.</p>

<p>Haha, I remember how the .999...= 1 thing made me dizzy when I first came across it.</p>

<p>Keep in mind that they mean .9999999999 with an infinite number of 9's. I bet we're just calculating a limit or something, but I'm not in a Calculus mood right now.</p>

<p>1+1=11 (10 chars).</p>

x + 2 = x
-x -x
2 = 0

LOL. This will work for any number. Basically anything can end up equal to zero. HAHA.</p>
