### 1/infinity = 0 is equivalent to 1/0=infinity?

It is now the time to discuss some funny thing. I just learn from GR class this morning a proof of the following statement

$\displaystyle \frac{1}{\infty}=0 \quad \Longleftrightarrow \quad \frac{1}{0}=\infty$.

Okay, let us start with the left hand side. By rotating 90 degrees counter-clockwise both sides of

$\displaystyle \frac{1}{\infty}=0$

we get

$\displaystyle -18=0$.

Now adding both sides by 8 we arrive at

$\displaystyle -10=8$.

Again, rotating 90 degrees clockwise both sides we reach to

$\displaystyle \frac{1}{0}=\infty$.

The reverse case can be treated similarly.
