How can 1=2  27 Oct 2009
If we have a = b then
a^2 = ab a^2 – b^2 = ab – b^2 (a + b) (a – b) = b (a – b) a + b = b 2b = b as a=b 2 = 1 Which Law of Maths is violated if any ? 
Re: How can 1=2  27 Oct 2009
at (a+b)(ab)=b(ab), when you got result a+b=b you divided by zero. if a=b, then ab=0.

Is it commutative law?
as if a = b then b=a right?

My Alg II teacher taught me the same basic thing in 11th grade:
x=1 x*x=x*1 x^2=x x^21=x1 (x+1)(x1)=(x1) x+1=1 1+1=1 2=1 same thing, different variables

For one more such fallacy, using Complex Numbers ;), see http://www.math.toronto.edu/mathnet/...econd1eq2.html.
