Shortest math joke

Let ∈ < 0.

We should probably be worrying more if we do get it. tongue


Why did the vector cross the road?
It wanted to be normal.

Re: Shortest math joke

In dealing with limits, sets, and sequences, just about every single proof starts off with the line:

Let ∈ > 0.

It reached a point where ∈ is pretty much just assumed to be a positive real number.
