A proof that 1=2?

Hey, ppls can ya spot the mistake?

Is it true that:
a = a
quadrating
a^2 = a^2
substracting a^2 from both sides
a^2 - a^2 = a^2 - a^2
using formulaes
(a-a)(a+a) = (a-a)a
erasing same elements(a-a)
a+a = a
finaly
2a = a
erasing same elements(a)
2=1

How you doin'? :H

 

(a-a)(a+a) certainly not = to (a-a)a

Im doin fiiine. How you doin..?

 

lol yeah, i spotted that right away.

 

Yeah, same. I'll bet a stoner made that one, haha.

Peace and love

Gives ZERO = ZERO!

yes...

meaning, "divide by (a-a)"

But... this is a DIVIDE BY ZERO.

Another way of looking at it:

This is like saying:
0 = 0
0 * 1000 = 0 * 1
1000 = 1

In other words, if two things multiplied together give zero, then one or the other must be zero, (or both) and this tells you nothing about the other thing.

But, you've got a nice little trick here.

 

Thank you mighty_thor!!! Only you understood my trick
BTW its a good one " 1 = 1000"
Peace

 

ok I dont understand one fucking thing of this

 

All you've proved is that you can't divide by 0.

 

proof positive that stoners cant do simple algebra
