The second statement is false.
if x = y, then x2 does not equal xy; x to the second power equals xy.
For example: if 1=1 then 1(2) does not equal 1(1)
Bullshit from the start, not to mention the division by zero

Sorry guys but second line is false its only true when x=1 or 2
x = y.
Then x2 = xy is wrong if x=3 , xy=9 x2=6 6 !=9
you can't divide this way if its proper algebra left side is
x2 - y2 2(x-y)
------- = ------ = 2 <- left side of the equation
(x-y) (x-y)
and obviously you cant separate (x-y) from the right side (xy - y2)/(x-y) != y
sorry guys example is flawed and 1 != 0

Unfortunately, this "proof" falls apart at the 2nd line. x2 = xy only holds true for 0, 2, and -2. The correct equation is x^2 = xy.
Still, a pretty interesting use of mathematics in an attempt to destroy all of our beliefs in what is thought to be true.

This appears to work, but only because you are dividing by zero since (x-y) is, by definition of the first line, equal to zero.
|
|
|
|
|
huh? I don't think x = y implies x2 = xy. How did you get that?
|
|
|
|

"x2" is supposed to mean x squared.

As has been pointed out here, at some point you're dividing erroneously. But, you can prove that 0 = any number you want, using the derivation of differential calculus, as described here[^]: if you plug numbers into the equation at stage 3, you can "prove" pretty much whatever you want to prove. But of course, math is a language, not reality - and you can speak nonsense in any language.

If 1 = 0, then 1 - 1 = 0 - 1, which means -1 = 0. Contradiction, so 1 = 0 can't be true.

This is a code site so I wanted to prove this with C# and it fell apart for me.
[TestMethod]
public void TestMethod1()
{
var y = 5;
var x = y;
Assert.AreEqual(x * 2, x * y);
}

Sorry, that doesn't work.
x2 is NOT equal to xy. That's like saying 2x = x*y which is ONLY true if x and y are both 2.
Cute, but does not float.

Why do so many people here fail to grasp the obvious, that "x2" is meant to represent x squared? It's almost as if the CP community isn't very high quality.

Well, the first problem with this is
x = y
then x2 = xy IFF x = y = 2
This was stated just above, but I didn't get that far when I was reading the comments...

Seeing you're playing with polynomials there, aren't you?
following the logics..
x = y
x^2 = xy
x^2-y^2 = xy-y^2
(x-y)(x+y) = (x-y)y
x+y = y
2y = y
however you draw the wrong conclusion here, go on like this:
2y-y = y-y
y = 0
|
|
|
|
|
You can't divide any number with 0. (x-y=0)
Divide by 0 is infinity, and infinity can't be equated.
|
|
|
|
|
x-y=0. You are dividing by 0. Therefore your theorem falls apart at that point.
Nice try.

"x2 = xy"
This is VERY wrong, I guess?

If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.
