To go along with the .999... =1 thread I thought I'd contribute my own mess. Today I'll prove that 1=2<br><br>
We have 2 variables A and B where A and B are equals.<br>
A = B<br>
A^2 = AB<br>
A^2 - B^2 = AB-B^2<br>
(A-B)(A+B) = B(A-B)<br>
A+B = B<br>
B+B = B<br>
2B = B<br>
2 = 1<br><br><br><img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink"><span style="color:#FFFF00;">If you know the answer, shhh.....</span>

That just goes to show ya...not all theorems should be in bed at the same time.<br><br>
EDIT: Actually....<br>
A+B = B<br>
A+B-B=B-B<br>
A=0

highlight to see the answer <img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin"><br><br>
and you may want to change A2 to A^2 to avoid confusion<br><br><span style="color:#FFFFFF;">division by zero<br><br>
between steps 4 and 5 you divide each side by (A-B) which equals zero<br><br>
old trick</span>

If 2 = 1. And 1 = 0.099... Then 2 = 0.99...

I went to a futher mathematics meeting where they did 0.999 = 1. No one could give a valid reason why it wasn't true. There is a mistake in the 1 = 2 one, but I'm too tired to work it out.

I'll show 0.9999...=1, but I won't give away the 2=1 just yet.<br><br>
0.9...=x<br>
10x=9.9...<br>
-x -0.9...<br>
9x=9<br>
x=1

actually. .999999 repeating = 1, but 1!=2 because you divided by A-B wehre A=B, therefore A-B=0, and you can't divide by 0.<br>
and 1=.99999999.... because there is no number between them. between 1 and 2 there is 1.5, 1.25, 1.125 etc, you keep going. but there is nothing between 1 and .99.... therefore they are the same.
