Besides, if you want to place a zero denominator on one side, you must place the entire side over zero, not just one number or the other. Then do the same to the other side of course (as in, the entire side). 0 x 1 = 0 x 2 so 0/0 x 1 = 0/0 x 2? Nope. This is how it goes: (0 x 1)/0 = (0 x 2)/0 Both sides equal 0 and thus, 0 = 0, not 1 = 2. And technically speaking, division by zero is possible but ONLY when the numerator is zero or at least comes out to zero.

you multiply both sides with a, you don't square both sides. and the post was to show that 2!=1, since you divide by zero when dividing (a-2) from both sides) That still comes out to 4 a = 2 a x a = 2 x a a still = 2 so 2a = 4 There's no getting around it buddy, sorry. And the rest of your math is still wrong.

'nother classic version of the "2=1" with division by zero a = 2 a^2 = 2a irrelevant from here on due to error in step 2 If a = 2 then a^2 = 2^2 = 4, not 2a. Where the hell do you stoners come up with this? Please stay as far away from college as humanly possible.

I believe the OP's premise was x = 0.999...(infinite amount of decimals), not x = 0.999, just to get the numbers right. That makes no difference. His math is still incorrect, regardless of decimal places.

Not the brightest crayon in the box are ya? x = .999 10x = 9.99 (get a calculator if you don't believe me) 10x - x = 9.99 - .999 9x = 8.991 x = .999 Right back where we started, not 1. 0 x 1 = 0 0 x 2 = 0 and 0 x 2349048579875948545 = 0 also So 1 = 2 = 2349048579875948545? More like 0 = 0. LoL ohhh kids these days...

I think that's enough of the electrics guys, thanks.
