 * $$\begin{align}

0\times 1 &= 0 \\ 0\times 2 &= 0. \end{align}$$


 * $$0\times 1 = 0\times 2.\,$$


 * $$\textstyle \frac{0}{0}\times 1 = \frac{0}{0}\times 2.$$


 * $$1 = 2.\,$$

The fallacy is the implicit assumption that dividing by 0 is a legitimate operation with $$0/0=1$$.


 * $$\begin{align}

(x-x)x &= x^2-x^2 = 0 \\ (x-x)(x+x) &= x^2-x^2 = 0 \end{align}$$
