UPJOKE

### One time my math professor asked everyone in class to write a complex number on their forehead

You could probably imagine the expressions on our faces.

### Complex numbers are complicated.

Please tell me I’m just imagining things.

This joke may contain profanity. 🤔

### There is no I in Complex Numbers

I guess that's why I failed this class.

### Complex numbers are all fun and games....

....until someone loses an i....

The first four clutch their heads in pain, but 1-i keeps going.

When -2 asks him how he walked through it, he shrugs and replies

"I'm imaginary".

### Perplex Numbers

I was talking to my physics professor the other day, and some theoretical work he did with tachyons came up. A tachyon travels faster than light, and in order to use some of the math from special relativity, one had to define what he called "perplex numbers"--numbers with negative absolute value. He...
