   –2=–2
   =>1–3=4–6
   =>1²–2×1×3/2=2²–2×2×3/2
   =>1²–2×1×3/2+(3/2)²=2²–2×2×3/2+(3/2)²
   =>(1–3/2)²2–3/2)²
   =>1–3/2=2–3/2
   =>1=2

      I asked my friend, who is a mathematician.
      This was his reply, "Error is in line 5.  There's a sad face there.  It should be a happy face."
      I don't know if he was kidding or not.

         The problem is not there. But how the notice is not bound by anything that has been hardened in people's minds.

   It is because the two sides of the equation are not equal.

      My friend said your comment was useless... lol... although he said "kind of" probably to soften the blow.

   Oh, ok... ignore the last post... here is the actual deal.
   
   "My actual solution would be to replace line 6 with
   =>(-1/2)^2 = (1/2)^2
   =>1/4 = 1/4"
   
   Now tell me it's right so I can move on!

   line 5: (1-3/2)² = (2-3/2)² correct
   => (-0,5)² = (+0,5)²
   => 0,25 = 0,25
   line 6 game over :-)
   however what is possible:
   1x(-0,5)²= 1x(0,5)²
   => 1 = (0,5)²/(-0,5)²
   => 1 = (0,5/-0,5)²
   => 1 = (-1)²

   Last line; one does not equal two.  Unless it's not mathematics but some sort of heart-felt philosophy.  Looks like mathematics to me, but I'm no Einstein.

   replace line 5 with:
   
   =>|1–3/2 |= |2–3/2| or
   
   =>-|1–3/2| = -|2–3/2|
   When you took the sqr root of each side in the preceeding step to produce this one, you assigned a negative value to one side and a positive to the other.  As that function has two possible answers, you must specify which one is applicable.

   Barack Obama = man
   Nasrullah Idris = man
   
   Barack Obama = 2
   Nasrullah Idris = 1
   man = x
   
   so
   2 = 1

      That's not math. That's bull shit like the anything equals anything logical fallacy....which is essentially what you're using if you randomly equal anything to a mathmatical symbol and then treat it like math.
