Criminal :P You just divided both sides of the equation with 0! What your doing was solving the double equation: x = y AND x̢̮â¬Å¡Ãâò-y̢̮â¬Å¡Ãâò=(x-y)(x+y) You got the answer 1 = 2, which is false. This means, that there is no root to this equation. So even if you did get this far without cheating, it wouldn't prove anything. (according to what i've learnt in high school lol) Yeh I have the same problem with Dittos. I don't do maths in english :oops:
