John was first to answer the question so he gets the choice of either a PSoCEval1 or a signed copy of my Lab Book.   So John, please send me your address by e-mail.

2     X^2 = X * Y

3     X^2 -Y^2  = X*Y - Y^2

4     (X + Y) * (X - Y) =  Y * (X - Y)

5    (X+Y)  = Y

6    (Y + Y) = Y  (substitution from 1)

7    2 = 1
